What is the largest and smallest battery bank one can use with Any-Grid PSW-H Inverters?

When it comes to pairing battery banks with your Any-Grid PSW-H inverter, the main thing you need to consider is nominal voltage. That is, if you have a 24 Vdc inverter, make sure that you have a 24 Vdc battery bank. In terms of bank size, theoretically there is no upper limit, but there is a practical one. This is heavily influenced by overall system size, budget, and of course space. Whatever your battery bank size may be, it is important to have a good quality bus bar and correct wiring cross-section. As for the minimum size, we recommend at least 200 Ah of battery capacity per PSW-H, if lead-based batteries are used. For lithium batteries smaller battery sizes may be usable, but make sure the battery and its battery management system (BMS) can handle the current requirements of the inverter(s) for both charging and discharging.
