Free load audit — sizing estimate for your inverter, battery and solar array
Tell us what's plugged in at your place — we'll work out the exact inverter, battery and solar array size you need, free, with a copy emailed to you for reference.
Search or tap to add appliances. You can add as many as you need.
We understand that 1HP = 746W — but the HP on an AC or pump tells you its cooling/pumping size, not its motor's mechanical power. That's true for every brand, everywhere, not just ours. What actually determines electricity use is the unit's efficiency rating. Industry data puts a 1HP-class AC at 750–1,100 watts of real power draw — we use 1,000W, right in that documented range.
Fill in a name and power rating first.

Is your supply single-phase or three-phase?
Most homes and small offices in Nigeria are single-phase. Three-phase usually means a larger commercial load, or a three-phase meter already supplied by your DisCo.
Please select Single-phase or Three-phase above before continuing.
Hybrid or Off-grid?
Hybrid — you still have grid/generator as backup, so your battery only needs to bridge the gap until power returns. Off-grid — no grid or generator at all; your battery and solar must cover every day on their own.
Please select Hybrid or Off-grid above before continuing.
How many days of backup autonomy do you want?
Current: 1 day(s). Select "Off-grid" above for this to affect your battery and solar sizing — Hybrid systems rely on grid/generator for extended outages, so this control has no effect until Off-grid is selected.
What system voltage do you want?
Not sure? 48V is the most common choice for modern Nigerian homes and offices — it handles bigger loads at lower current, which means thinner, cheaper cabling.
Lead-acid or Lithium battery?
Lead-acid — the type most Nigerians already know (like a bigger car/UPS battery). Cheaper to buy now, but heavier, needs more space, and typically lasts 2–4 years with regular generator/PHCN-backed charging. Lithium — new and improved battery model. Costs more upfront, but smaller, lighter, and typically lasts 8–10+ years with less maintenance. Often works out cheaper over the system's lifetime, especially if you're cycling the battery daily.
Which battery type?
Based on your last two answers — this list narrows automatically to what's actually compatible.
Where is this installation?
We use real sun-hour data for your state to size the solar array correctly — sun exposure genuinely differs across Nigeria.
What solar panel wattage do you plan to use?
Not sure? Leave the default — this only changes how many individual panels make up your array, not the total solar capacity you need.

Sizes above 5kW may be reached by cascading two or more inverters together — cascaded units must be the same size, brand and model.
A lower-cost option. May not reliably start larger appliances like AC, pumps, or freezers — Standard is recommended if you have any of these.
Sized with a safety minimum for appliances known to draw a lot of power when starting (AC, pumps, freezers).
We recommend V for this system — it will support your appliances more reliably and perform better than V here. Please select V above to see your inverter and battery recommendation.
Your load is large enough to be better served by a high-voltage DC system (200–800VDC) rather than our standard cascaded inverter range — this reduces current and cable losses significantly at this scale.
