In this article we will explore the Fronius Gen24+ and BYD solar battery package.
Solar Batteries
AC and DC Coupled Batteries
In short, AC coupled solutions are fantastic retrofit options that allow you to add a battery to any existing solar system. These batteries operate as a stand alone unit. Examples being the Tesla Powerwall and Sonnen EVO.
DC coupled solutions use a Hybrid inverter. The hybrid inverter operates both your solar panels and your battery system. This all in one solution leads to higher efficiency and improved performance.
The main points of differences between AC and DC coupled batteries:
AC Coupled Batteries
-
Less efficient because of many DC-AC / AC-DC / DC-AC conversions
-
Battery is more expensive because of the built-in battery inverter
-
Good for retrofitting on to existing systems.
DC Coupled Batteries
-
More efficient. Only 1 conversion
-
Battery is more affordable. No built-in battery inverter required
-
Can ‘Supersize’ the array because of simultaneous AC output & DC battery charging
Fronius Gen24 plus
Fronius are a European company with their manufacturing facilities in Austria. They have been in business for over 70 years and are the go-to brand for most Australians when installing Solar.
Their latest inverter the Fronius GEN24+ comes in both Single-Phase and Three-Phase models. Sizing from 3kW up to 10kW and is a true Hybrid with full backup functionality when combined with a BYD battery.
Also without a battery the Fronius GEN24+ has a basic backup power supply (PV Point). This is a power point supplied with solar in the event of a power outage. This supplies loads with up to 3 kW of solar power. The PV Point represents a low-cost backup power solution.
Since the success of the Fronius Gen24+, Fronius have released the Fronius GEN24 . This inverter is hybrid ready, so if you don’t want a battery straight away you can prepare in advance.
Fronius is long lasting, one of the main reasons is thanks to active cooling. Resulting in the Fronius GEN24+ offering a longer service life and increased yield due to better performance.
BYD
-
1st place in the HTW Berlin Energy Storage Inspection Study
-
Winner of the German Design Award
-
Winner of the Intersolar Award
-
Winner of the Red Dot Design Award
-
Winner of the Plus X Award
-
Lithium Iron Phosphate (LiFePO4). Which is the leading lithium chemistry. Allowing a greater depth of discharge, less degradation over time, and higher safety
-
Modular battery structure allowing users to start from 8.3kWh of storage up to 66.3kWh
-
Full back up available on both Single and Three Phase, not just a backup circuit
-
One of the highest charge and discharge rates from 2.56kW to 9kW (See chart below)
-
Ability to oversize the panel array up to 15kW. Allowing more power to both the home and battery and preventing power exporting to the grid.
-
