Estimate
Total load357 W
Daily energy2.50 kWh
Inverter1000 VA (1.0 kVA)
Battery3.5 kWh ≈ 145 Ah at 24 V (lithium)
Solar panels750 W ≈ 2 × 450 W panels
Est. runtime on battery alone7.0 h at full load
Accessories: charge controller (if not hybrid), MC4 connectors, solar cable, DC breakers, surge protection, mounting structure.
Installation: required by a qualified solar installer.
Actual solar performance depends on sunlight, load, battery condition, temperature, cable losses and installation quality. This is an estimate, not a guarantee — exact runtime needs a verified site survey.
