Common Questions

Can I add more solar panels later?

Yes — the two inverters combined support up to 22,000W of solar input, well above the 13,280W (32×415W) included in this kit, leaving room to expand.

Can I connect more inverters together?

Yes — up to 6 identical SPH8048P inverters can run in parallel in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations.

What's the actual usable battery capacity?

25.6kWh combined from five 5,120Wh LiFePO₄ batteries in the included server rack cabinet, each rated for at least 7,000 cycles to 80% depth of discharge.

Are the batteries stored in a rack or individually?

This kit includes an enclosed server rack cabinet sized for all five 100AH batteries, rather than mounting them individually.

Do I need a licensed electrician to install this?

Given the scale of this system — dual inverters, a 25.6kWh battery bank, and 32 panels — installation should be handled by a qualified, licensed electrician familiar with your local code.

Finally energy independent – worth every penny

Installation took me and a friend a full weekend – the instructions were clear, and the kit came with almost all the connectors and cables you need. The inverter runs my whole workshop (table saw, dust collector, and fridge at the same time) without any hiccups. The 120V/240V output is perfect for the well pump and dryer.

Runs heavy loads with ease

I was skeptical about whether any off-grid system could handle my demands: a 4-ton AC unit, deep well pump, and my woodworking shop with table saw and dust collector. This 16KW kit handles it all effortlessly. The dual 8000W inverters provide massive surge capacity – my well pump''s startup surge over 10KW doesn''t even make the lights flicker.

16KW of pure off-grid freedom – zero utility bills

This kit is incredible! 32 panels (13,280W), 25.6kWh LiFePO4 batteries, and dual 8000W inverters. I''m generating 50-55kWh daily – enough for AC, well pump, appliances, and workshop. The split-phase 240V runs my whole house perfectly. Expandable design means I can add more later. Everything included: panels, batteries, inverters, cables, mounts. Best investment I''ve ever made for my off-grid home. 5 stars!

Works great

This solar panel kit is a good buy. The system works great and these panels seem very efficient even in indirect sunlight. I have recommended it to my friends.
