Frequently Asked Questions
What capacities does the APX battery come in?
Solar X offers the Growatt APX in 15 kWh and 20 kWh packages. The 15 kWh delivers 7.5 kW continuous with 12 kW peak, and the 20 kWh delivers 10 kW continuous with 16 kW peak, both for 60 seconds.
Is it safe to install indoors?
Yes. The APX uses cobalt-free lithium iron phosphate (LFP) chemistry with passive fuse and aerosol protection and an IP66 design, making it suitable for indoor spaces such as a garage or utility room.
Can I expand the system later?
Yes. The modular design supports soft-switching parallel connection, and you can combine packs of different capacities, production batches, and suppliers, so storage grows with your needs.
Which inverters is it compatible with?
The APX communicates over RS485 and CAN and works with major inverter brands. Solar X confirms inverter compatibility during system design.
How does it hold up in cold weather?
The APX operates across a wide -10 C to 50 C range, suited to Canadian climates when sited appropriately.
