Before choosing an inverter, confirm what supply your building has.
How to check
- Look at your meter: a three-phase meter usually shows three live inputs or L1/L2/L3 markings.
- Look at your main breaker: a three-pole (or four-pole) main breaker indicates three-phase.
- Ask your electrician, or send Battery World a photo of your distribution board on WhatsApp.
Single-phase sites
Most Kampala homes are single-phase. Options range from 3 kW (Deye SUN-3K-SG04LP1, GoodWe GW3000-ES) up to 18 kW on a single phase (Deye SUN-18K-SG01LP1) for large homes.
Three-phase sites
A single-phase inverter on a three-phase site can back up only one phase. To back up the whole building, use a three-phase hybrid: Deye SG05LP3 (3–20 kW, 48 V battery), GoodWe ET LV (5–20 kW, 48 V), GoodWe ET G2 (6–15 kW, HV) or Deye SG01HP3 (30–50 kW, HV).
