Will a battery actually raise your self-consumption?
A battery only lifts self-consumption when it shifts solar into the evening, not when it sits full for load shedding. How to check the real number on your own meter.
Battery and Backup Sizing
Battery capacity, depth of discharge, backup hours and essential load sizing for hybrid and backup systems.
Why a bigger battery barely moves your monthly bill
A battery does not make energy, it moves it. Here is the rands-per-shifted-kWh arithmetic that decides whether a bigger battery can lower your monthly bill.
How A Stage 4 Outage Really Tests Your Battery Bank
Stage 4 means about eight outage hours a day in four blocks. Here is how usable battery capacity, not the nameplate figure, decides what stays on.
Your big battery is only as fast as the inverter charging it
Your battery is only as fast as the inverter charging it. How C-rate, the PV-to-battery path and the winter sun window set your real system limit.
Why a 5 kWh battery is not five hours of backup power
Backup hours come from the essential load list, not the battery's sticker. How usable energy, depth of discharge and circuit choices set real run time.
What 5 kWh of LiFePO4 really runs in load shedding
A labelled load-list calculation showing what 5 kWh of LiFePO4 really runs during load shedding, with depth of discharge and inverter efficiency included.
