SolaX Power - Battery Reviews

About SolaX Power

Solax been around for a while, having its roots in a company called Suntellite Group, which established back in 2003. The Solax brand was established in 2012, and the firm has evolved into a multinational corporation with more than 2,000 employees worldwide. It started out producing hybrid inverters in 2013, and its first battery was released in 2017.

As with many solar battery companies, Solax headquarters are in China - but it also has offices in Netherlands, Germany, UK, Australia, Japan and the USA. The company established a subsidiary in Australia in 2014.

Solax Batteries

In Australia, Solax's major storage product family is the TriplePower. These are "plug and play" batteries with usable capacity up to 43.1kWh and charge/discharge power up to 23.2kW.

T-BAT-SYS-HV-5.8

This line of batteries starts off with a usable capacity of 5.1 kWh, but can be expanded with additional "slave" units out to 20.7kWh usable capacity. The master unit measures 474 x 193 x 708mm and weighs 72.2kg. The slave add-ons are 474 x 193 x 647mm and weigh 68.5kg.

Continuous power ratings range from 2.8 kW for the master unit, up to 11.5 kW for a fully expanded system. All use lithium-ferro phosphate (LFP/LiFePO4) chemistry cells and Solax says the batteries have a service life of more than 6,000 cycles.

These batteries can be floor or wall mounted, either indoors or outdoors.

Note that these Solax TriplePower batteries are only compatible with hybrid Solax inverters and are not off-grid capable.  As far as pricing goes, Solax are one of the cheaper lithium-ion battery systems available in terms of cost per warranted kilowatt-hour.

T-BAT-SYS-HV-S3.6

The base model of this LFP-chemistry battery line has 6.5kWh of usable storage capacity, but can be built out using stackable 3.6kWh modules weighing 33.5 kg each to 43.1 kWh (two stacks). Power ratings start at 3.5kW for the base model and increment up to 23.2kW for a 43.1 kWh system. IP65 rated, this battery is suitable for both indoor and outdoor installation.

Again, inverter compatibility is limited to Solax hybrid inverters.

Solax Recall

Some SolaX Power X-cabinet and PowerStation models (now discontinued) with cells supplied by LG Chem are subject to a recall. Affected systems may overheat and cause a fire. It appears Solax is no longer using LG cells as the battery chemistry of current TriplePower models is lithium-ferro phosphate (LFP/LiFePO4), and the LG cells were Nickel Manganese Cobalt (NMC).

Solax Warranty

Solax provides a 10-year warranty on its batteries. It guarantees the TriplePower will retain at least 70% of its nominal storage at the end of the warranty period. An interesting condition is when expanding a system. If the original battery is more than 1 year old, Solax needs to be contacted first for consent.

If you have a Solax system, share your thoughts on how it has been performing.
