Not all solar and battery systems in Perth are built from the same equipment. Behind the headline kilowatt figures and warranty years, there is a significant spread in the quality of panels, inverters, and batteries being installed — and an equally significant spread in the manufacturer support, training, and accountability that backs them up.
Positive Energy Solutions installs only mid-to-premium brand equipment from manufacturers with established Australian market presence, proven after-sales support, and genuine investment in their certified installer networks. This is not a marketing position. It is a deliberate operating model with real consequences for how your system is designed, installed, and supported over its life.
This post explains who Positive Energy Solutions partners with, what those partner relationships involve, and why the brand selection we make on your behalf matters far more than most buyers realise when comparing quotes.
1. Positive Energy Solutions’ Manufacturer Partner Relationships at a Glance
Partner status reflects Positive Energy Solutions’ current accreditation with each manufacturer. Certification requires ongoing training, installation volume benchmarks, and quality standards set by the manufacturer.
2. What Manufacturer Partner Status Actually Means
It is worth being direct about what a partner certification is and what it is not. It is not a badge that manufacturers hand out freely to anyone who places an order. Each of the brands Positive Energy Solutions works with operates a tiered accreditation programme that places genuine requirements on installers.
To hold and maintain a partner certification at any tier, Positive Energy Solutions must:
- Complete manufacturer-led training: This is product-specific, hands-on training — not a general solar course. It covers installation requirements, system configuration, fault diagnostics, and firmware and software management for each specific product range. The training is repeated and updated as products evolve.
- Meet installation volume benchmarks: Higher certification tiers require a minimum number of installations per year. This is how manufacturers ensure that certified installers are working with the products regularly enough to maintain genuine expertise, not just theoretical familiarity.
- Maintain quality standards: Manufacturers conduct audits, review installation documentation, and in some cases inspect completed jobs. Certification can be revoked. The tiers are meaningful because the requirements to hold them are enforced.
- Access to direct technical support: Certified installers have access to manufacturer technical support lines that are not available to the general public or uncertified installers. When a fault needs diagnosing or a warranty claim needs lodging, Positive Energy Solutions is dealing directly with the manufacturer’s technical team — not a generic customer service queue.
- Priority access to parts and firmware: High-tier partners typically receive priority access to replacement components and early access to firmware updates. This matters for how quickly a service issue can be resolved.
- First access to new products: High-tier partner status gives Positive Energy Solutions advance visibility of upcoming product releases — new battery models, inverter generations, and EV charger upgrades — before they reach the wider market. This means we can advise customers on what is coming, design systems that are compatible with future upgrades, and offer new products as soon as they are available in Australia.
The practical effect of all of this is that Positive Energy Solutions’ team knows the products they install at a level that most installers who simply order from a distributor do not — and when something needs attention, the path to resolution is direct and accountable.
3. The Six Brands Positive Energy Solutions Partners With — and Why
SunPower — Elite Partner
SunPower P-Series panels are the premium panel Positive Energy Solutions installs on every solar system. N-type TOPCon shingled-cell glass-glass construction, rated to 440–460 W per panel, with a 30-year product, performance, and service warranty. As a SunPower Elite Partner, we have direct access to SunPower’s technical and warranty support infrastructure — which is significant given that the 30-year warranty is only as strong as the relationship between the installer and the manufacturer behind it.
SunPower panels are supplied to Positive Energy Solutions directly, without a wholesale intermediary. This gives us direct accountability on every panel supplied and installed, and direct lines of communication if a panel issue ever arises.
SigEnergy — Gold Installer
SigEnergy’s SigenStor system is one of Positive Energy Solutions’ primary battery and hybrid inverter packages. The SigenStor integrates solar generation, battery storage, and grid management through an AI-driven energy management platform. SigEnergy also manufactures EV chargers that integrate directly with the SigenStor — allowing smart, solar-aware EV charging as part of a fully managed home energy system. As a Gold Installer, we have completed SigEnergy’s advanced training programme across the full product range.
The SigenStor is a relatively new product to the Australian market, which makes installer expertise particularly important. Positive Energy Solutions’ Gold Rated status means the team installing your SigenStor system has been trained directly by SigEnergy — not just following a generic installation guide.
Fronius — Solutions Partner Plus
Fronius is one of the most respected inverter manufacturers in the world, with a long track record of manufacturing in Austria and a strong Australian market presence. The Fronius GEN24 PLUS hybrid inverter and Fronius Reserva battery are premium products positioned at the quality end of the market. As a Fronius Solutions Partner Plus, Positive Energy Solutions has completed Fronius’s technical training programme and is accredited to install and service the full GEN24 PLUS and Reserva product range.
Fronius also manufactures the Wattpilot EV charger, which integrates with the GEN24 PLUS inverter for solar-optimised EV charging — automatically prioritising surplus solar generation to charge your vehicle before feeding the grid. Positive Energy Solutions is accredited to install the full Fronius ecosystem, including Wattpilot.
Fronius’s partner network in Australia is deliberately selective — Solutions Partner Plus status is not available to all installers who want it, and maintaining it requires consistent standards.
Sungrow — Platinum Partner
Sungrow is the world’s largest inverter manufacturer and one of the most established battery brands in Australia. The Sungrow SBH battery system and SH series hybrid inverters are proven products with an extensive installed base in Perth. As a Sungrow Platinum Partner — the highest tier in Sungrow’s Australian installer programme — Positive Energy Solutions has access to Sungrow’s priority technical support channel, advanced training, and direct escalation paths for warranty and service matters.
Sungrow also manufactures EV chargers that pair with the SH series hybrid inverters, enabling solar-optimised charging that draws from generation and storage rather than the grid. Positive Energy Solutions installs the full Sungrow product range under its Platinum Partner accreditation.
Platinum Partner status with Sungrow requires sustained installation volume and ongoing training compliance. It is a recognition of both expertise and commitment to the brand.
Tesla — Certified Installer
Tesla’s Powerwall 3 is the most recognisable home battery in Australia. As a Tesla Certified Installer, Positive Energy Solutions is approved to supply and install the Powerwall 3 and has completed Tesla’s installation and commissioning training. Tesla’s Certified Installer programme is controlled — Tesla manages who is permitted to install Powerwall systems in Australia, and certification requires training, quality standards, and ongoing compliance.
Tesla also manufactures the Universal Wall Connector EV charger, which works with all EV brands and integrates with the Powerwall 3 for smart, solar-optimised charging. For customers running a Tesla Powerwall 3 alongside an EV, this creates a tightly integrated home energy and charging system. Positive Energy Solutions is accredited to install both.
For customers who have already decided on a Tesla Powerwall 3, Positive Energy Solutions’ Certified Installer status means the system is installed by a team that Tesla has vetted and trained, with access to Tesla’s installer support channel.
iStore — Elite Partner
iStore is Australia’s leading heat pump water heater brand, and Positive Energy Solutions is an iStore Elite Partner. Beyond heat pumps, iStore also manufactures hybrid inverters, battery storage, and EV chargers — making it a full home energy ecosystem brand, not just a hot water specialist. For households making the move to all-electric energy, iStore covers hot water, energy storage, and EV charging as an integrated product family. Elite Partner status requires training across iStore’s full product range.
The iStore heat pump pairs naturally with a solar and battery system, allowing hot water to be heated from solar generation during the day and reducing the load on the battery overnight. Positive Energy Solutions designs these systems as integrated units, not add-ons.
4. Why Positive Energy Solutions Does Not Install Budget or Tier-3 Brands
The Perth solar market includes a wide range of panel, inverter, and battery brands — from the manufacturers listed above to lower-cost alternatives with limited Australian presence and thinner warranty backing. Positive Energy Solutions does not install budget or tier-3 equipment, and the reasons go beyond product quality alone.
- Warranty claims need a manufacturer behind them: A 10 or 25-year warranty is only meaningful if the manufacturer is still operating, still servicing the Australian market, and still has the infrastructure to honour the claim. Several budget solar brands have exited the Australian market since 2020, leaving customers with warranties that cannot be honoured. Positive Energy Solutions only installs brands with long-term Australian commitment.
- After-sales support requires a local presence: When a fault needs diagnosing, a replacement part needs sourcing, or a firmware update is required, a manufacturer with a local Australian team responds in days. A manufacturer operating from overseas with no local service presence may take weeks — or may not respond at all. Every brand Positive Energy Solutions works with has genuine Australian market infrastructure.
- Installer certification requires training: The partner programmes Positive Energy Solutions participates in require genuine product training. This means our team understands the equipment it installs at a technical level — not just how to mount panels on a roof, but how each product’s energy management, monitoring, and protection systems work. This formal installer programme, training requirement, and quality accountability are what a premium brand partnership guarantees.
- Long-term performance depends on quality manufacturing: Premium brands invest significantly in manufacturing quality, R&D, and product testing. The difference between a premium battery that cycles well for 15 years and a budget battery that degrades noticeably in year five is real, and it compounds over the system’s life.
The short version: every extra dollar spent on a mid-to-premium brand pays back through fewer service events, stronger warranty backing, and a system that performs as specified across its full design life.
5. What This Means for You as a Positive Energy Solutions Customer
The practical benefits of Positive Energy Solutions’ brand selection and partner status flow directly to the customer.
- You are getting equipment the installer knows inside out: Every brand Positive Energy Solutions installs is a brand its team has been specifically trained on by the manufacturer. This matters for system design, commissioning, and any future fault diagnosis.
- Your warranties have a clear path to resolution: When a warranty matter arises, Positive Energy Solutions’ direct relationship with the manufacturer means the escalation path is short and accountable. For warranty matters, the customer contacts us; we work directly with the manufacturer’s technical and warranty team.
- Omnidian monitors every system: Every Positive Energy Solutions installation is enrolled in Omnidian’s performance assurance programme. Omnidian monitors output continuously and contacts you directly if a performance issue is detected — before you notice it yourself. This ongoing oversight is only possible with equipment from reputable manufacturers whose monitoring APIs and data feeds Omnidian can integrate with.
- You are protected against obsolescence: Manufacturers in Positive Energy Solutions’ partner network have Australian support infrastructure, stock replacement parts locally, and issue firmware updates to keep products compatible with grid standards as they evolve. That ongoing local support means your products can be serviced and updated as market requirements change.
- First access to new products: Positive Energy Solutions’ partner status gives it advance access to new product releases from each manufacturer. When a new battery model, inverter generation, or EV charger upgrade becomes available in Australia, our customers hear about it first — and we can advise on upgrade pathways before products are widely available through the broader market.
- 10-year workmanship warranty: Positive Energy Solutions backs every installation with a 10-year workmanship warranty. The premium equipment installed and the manufacturer partner relationships behind it make this warranty meaningful — not just a number on a contract.
6. See the Brands in Person at the Positive Energy Solutions Showroom
Positive Energy Solutions operates a Perth showroom where you can see the equipment, speak to the team, and ask questions before making any decisions. This is one of the clearest differences between a business that is genuinely invested in its local market and one that exists primarily as a sales operation.
When you visit, you are meeting the same people who will design your system, install it, and be available for support afterwards. There is no overseas call centre, no call queue, no third-party service team. The relationships Positive Energy Solutions has built with its manufacturing partners translate directly into the level of knowledge and accountability that the local team brings to your project.
Whether you are early in the research process or ready to compare quotes, the Positive Energy Solutions showroom is worth a visit. Come and meet the team, see the equipment, and get an honest assessment of what suits your home.

Frequently Asked Questions
What does it mean to be a certified or partner installer?
Manufacturer partner and certification programmes require installers to complete product-specific training, meet installation volume benchmarks, and maintain quality standards set by the manufacturer. Higher certification tiers indicate greater investment in training and track record with the product. It is not a self-declared badge — manufacturers audit and enforce the requirements, and certification can be withdrawn.
Why does Positive Energy Solutions only install certain brands?
Positive Energy Solutions deliberately limits its product range to brands with proven Australian market presence, strong warranty infrastructure, and formal installer accreditation programmes. This allows our team to maintain deep product knowledge, access direct manufacturer technical support, and provide customers with warranties that have a genuine path to resolution. Budget and tier-3 brands are not installed because they cannot offer the same level of after-sales accountability.
Does Positive Energy Solutions sell solar without a battery?
No. Positive Energy Solutions installs solar and battery systems together on every project. With Synergy’s DEBS feed-in rate at 2 cents per kilowatt-hour, a solar-only system has a weak financial case for most Perth households. We design every system to maximise self-consumption through battery storage.
Can I choose my preferred brand from Positive Energy Solutions’ range?
Yes. Positive Energy Solutions offers systems using SunPower P-Series panels with SigenStor, Sungrow SBH, Fronius Reserva, or Tesla Powerwall 3 battery options depending on your phase connection, energy profile, and preferences. We will recommend the most suitable configuration for your home, but the choice is yours to make.
Does Positive Energy Solutions install EV chargers and heat pumps?
Yes. Beyond solar and battery systems, Positive Energy Solutions installs EV chargers and iStore heat pump water heaters. For households making the move to all-electric energy, we can design and install a complete solution — solar, battery, hot water, and EV charging — as a single integrated project. Each product is from a brand we are formally accredited to install.
