SolaX Power solar batteries reviews

One of Solax Power's goals is to be a world leader in battery storage development, production and distribution. That's pretty honest - some companies just outright claim to be even when it's clear they aren't.

As with many solar battery companies, its headquarters are in China - but Solax also has offices in Australia, the UK, Germany, The Netherlands and the USA. It's been around for a while, having its roots in a company called Suntellite Group back in 2003.

New generation Solax solar batteries are manufactured in partnership with a giant of the storage world, LG Chem (battery cells); so that provides a bit of reassurance.

In Australia, one of its major storage products is the TriplePower, a "plug and play" battery with scalability of capacity (to 25.2kWh) and charge/discharge power (to 6kW).

At the time of writing, Solax TriplePower batteries were only compatible with Solax inverters and are not off-grid capable. 

The other product is the all-in-one Solax Power Station, comprised of a cabinet housing an X1-Hybrid inverter (SK-TL) and one or two 3kWh or 6kWh batteries. The battery modules are also from LG and are NMC chemistry type (nickel manganese cobalt oxide). NMC tends to have a shorter cycle life and degrades more rapidly than another popular chemistry, LiFePO4 (Lithium Iron Phosphate). 

This battery has back-up, but not off-grid, capability.

Additional specifications of  Solax Power Station can be found on our solar battery comparison table.

As far as pricing goes, Solax are one of the cheaper lithium-ion battery systems available in terms of cost per warranted kilowatt-hour.

Solax Warranty

Solax guarantees the TriplePower will retain at least 60% of its nominal storage with 90% DOD (depth of discharge) for either 120 months after the commissioning date or for a minimum energy throughput of 13.5MWh (4.5kWh battery) or 18.9MWh (6.3kWh) - whichever comes first. However, an on-site inspection by a suitably qualified technician is required following sixty months of continuous use; which is probably a pretty good idea anyway.

For the Solax Power Station, there's a 5 year inverter warranty and 10 year battery warranty. It's not clear what the cabinet warranty is and other warranty details are also murky as the company doesn't have a related document on its web site.

We haven't seen these batteries in action over an extended period, so if you have a Solax system, share your thoughts on how it has been performing.
