DC Coupled Solar Batteries

DC Coupled batteries are the most common solar battery installed in Perth. They use Hybrid inverters that manage both the solar and battery. This all-in-one solution greatly improves efficiency and allows for super sizing solar systems.

These solar batteries are usually modular allowing more accurate sizing for the consumer. Battery sizing can start from 5kWh up to 100kWh+

The main benefits are as follows:

-Higher efficiency with only one conversion
-Greater functionality for single and three phase
-Greater battery backup and black start capabilities
-Can supersize the solar array to increase the total solar yield
-More affordable as a 2nd inverter is not required

Positive Energy stock the following DC coupled batteries

 

DC coupled battery prices start from $6,990
AC Coupled Solar Batteries

AC Coupled batteries retrofit with existing solar panel systems. They have their own built in inverter that converts and stores AC power into DC power. If you already have solar then AC coupled batteries are usually the best solution.

The main benefits are as follows:

-Compatibility with all existing solar systems
-More flexible battery installation locations

However AC coupled options are less efficient.
They are single phase solutions, the can sometimes be installed on three phase but the backup options are reduced.

AC coupled solutions are usually more expensive due to the extra built in inverter.

Positive Energy stock the following AC coupled batteries

AC Coupled battery prices start from $10,490
Solar and Battery Packages

One in three new solar systems installed by Positive Energy are Solar and Battery packages. These solar solutions contain solar panels, inverters, batteries and smart meters. 

Positive Energy focus on the mid to premium solar panel market. We stock the following solar panel manufacturers: SunPower, Winaico, Trina, Jinko and Canadian Solar.

The price of a solar battery package depends on the combination of equipment being installed. As well as the individuals needs and requirements. Like Solar panels there is no one size fits all solution.

Positive Energy will assess each customers needs. Resulting in the correct solar and battery solution.

Battery Storage

STORING YOUR SOLAR

There are many benefits of having a solar and battery system on your home or office. Including storing  power in a battery and having protection against power outages.

Sonnen-Solar-Battery

Battery Backup

There are a few things to consider when choosing a solar battery if the goal is to allow for battery back up and black start.

With battery backup it is important to know what appliance you want to operate in a power outage. We usually backup, lights, fridges and freezers and NBN. Almost all batteries allow for this solution.

When backing up larger loads ensure the battery is capable of providing power and the battery charge will last. For example you would not want to backup a ducted air conditioning unit with a 32A startup if the battery output is only 16A.

Also if the battery is only 10kWh and the load backed up is going to draw 4-5kW the battery would only last for 2 and a bit hours.

In conclusion be careful with what you backup and pick the right solution. Our consultants are able to help you with designing this process correctly.

If you would like to backup large three phase appliances. Positive Energy recommend the Fronius GEN24 with the BYD HVM or the Sungrow Inverter and battery combination.

Battery Black Start

Black start allows the solar panel system to “wake up” if the power grid is down when the sun rises in the morning. The solar panels then begin to recharge the battery and provide power to the backed up circuits.

Not all batteries have this functionality. Please consult us if this is an important feature before making a purchase.

It is worth noting that single phase batteries will not black start three phase inverters. Also they will only backup appliances on the phase they are connected to.

If you would like black start on three phase properties, Positive Energy recommend the Fronius GEN24 with BYD and the Sungrow inverter and battery combination.

WARRANTIES

Solar Battery WARRANTIES

Like all products the life expectancy of batteries vary as do the warranties. So what are some things to look out for?

How long does the manufacturer guarantee the product will remain functional? 
Most home batteries have a 10 year warranty. But it is also worth looking at the total throughput. You will find some batteries guaranteeing 35mWh of storage and the lower end of the market may only guarantee 15mWh.

What is the guaranteed output at 10 years? 
Most batteries guarantee 80% output after 10 years. However be cautious of cheap batteries that only guarantee 50-60% in the same time.

What is the guaranteed battery cycle?
Some battery manufacturers like Sonnen are designed to have 10,000 complete cycles. Other battery manufacturers life expectancy can be as low as 3,500 cycles.

Are the cycles are complete cycles not partial cycles?
If the battery manufacturer states 10 years or 3,500 cycles. But counts partial charges as a cycle, then your warranty will expire quickly.

Below is an example of a good warranty from Sonnen.

Complete Recharge Cycle is:

(i) a full charge and a full discharge of the sonnenBatterie; or

(ii) partial charges and partial discharges of the sonnenBatterie which when aggregated together constitute a full charge and a full discharge of the sonnenBatterie. Follow the link to our Warranty Page.

The future of solar batteries

The future of battery storage is now. Very minimal changes have been made to the hardware in the last 5-6 years and battery storage has been common in Europe for over 10 years.

However we are beginning to see more integration between solar batteries and network providers. This integration can improve customers savings through time of use tariffs.

For example Synergy now have a “Midday Saver” and “EV” tariff that charges 8c per unit from 9AM to 3PM.

Using software such as Evergen, batteries can be programmed to ensure they have received a full charge before 3PM. This solution is especially useful on clouded winter days when sometimes the batteries do not receive a full charge.

The Evergen software is free for the user and compatible with most solar battery solutions from Positive Energy.

FAQs

frequency asked questions

There are many benefits of having a solar battery system on your home, lets explore some of the FAQs.

Solar battery prices start from $6,490. However, the price of a new battery depends on the brand, individual needs, and install requirements.

Pricing for Solar and Battery packages start from $11,990.

There are two main types of solar batteries: DC coupled batteries that use a hybrid inverter, and AC coupled batteries that retrofit with existing solar systems.

DC Coupled batteries only need one inverter that manages both the solar panels and battery. These are the most efficient batteries available

AC Coupled batteries retrofit with existing solar panel systems. They have their own built-in inverter that converts and stores AC power into DC power.

Yes, most batteries come with backup power. With battery backup, it is important to know what appliances you want to operate in case of a power outage. Typically, three circuits are backed up: lights, fridges and freezers, and NBN. For large three-phase appliances, Positive Energy recommends the Fronius GEN24 with the BYD HVM or the Sungrow Inverter and battery combination.

Yes, when a battery is connected. Black start allows the solar panel system to “wake up” if the power grid is down when the sun rises in the morning. The solar panels then begin to recharge the battery and provide power to the backed-up circuits. Black start works on DC coupled batteries and AC coupled batteries on single-phase properties.

Most battery manufacturers guarantee 80% output after 10 years. Most home batteries have a 10-year warranty. Some batteries are designed to have 10,000 complete cycles.

Lithium Iron Phosphate (LFP) batteries are generally preferred due to their stability, which prevents thermal runaway and fires. LFP batteries also have high current delivery and improved cycle life.

The future of battery storage is now. Minimal changes are being made to battery hardware compared to 5-6 years ago. However, there is increasing integration between solar batteries and network providers, which can improve customers’ savings through time-of-use tariffs.
