Questions to ask installers about the APX HV S2
- Which size suits my usage, and is that usable capacity or nominal capacity?
- Which inverter will it run with, and does my existing solar need to change?
- Will it keep power on in a blackout, and which circuits are backed up?
- What does the warranty cover, for how long, and is there a throughput or cycle limit?
- Where will it be installed, and does that location suit its protection rating?
- Can I add capacity later, and can it join a virtual power plant?
Our home battery guide explains each of these, and the battery cost guide covers what affects the price.
