Build a 10–20 kWh bank with 2–4 modules to run RO booster pumps and controls overnight — the natural battery partner for the Sol-Ark inverters on this page. Rack, cable kits and busbars available; ask about matched packages.
Frequently Asked Questions
How many modules do I need?
Each module stores 5.12 kWh. A typical off-grid water system uses 2–4 modules (10–20 kWh); whole-home backup usually starts at 3. We'll size it from your load list free of charge.
Which inverters can it talk to?
Closed-loop BMS profiles exist for Sol-Ark, Victron, SMA, Growatt, Deye and others — the inverter reads real-time state of charge directly from the battery.
Can I install it in a standard server rack?
Yes — it is a 19-inch 3U module. Pytes also offers matching cabinets and rails; note the 24.4-inch depth when choosing an enclosure.
Is it safe for indoor installation?
Yes — LiFePO4 chemistry with UL9540A fire-safety testing and UL1973 listing make it suitable for garages, utility rooms and equipment shelters per local code.
