How I escaped load-shedding for R50,000

Like most South Africans, I got fed up with almost constant load-shedding and decided to invest in an inverter and battery installation to keep most of my household powered during Eskom's rotational power cuts.

In all, the system was R49,968. It provides a peak output of 3kW and has 2.75kWh of battery storage. Solar Power sourced and installed the components.
 
Huh in May for R49k I got 2 4.8kw batteries and a 5kw inverter, throw on some panels and extras and it came up to 105k

50% depth of discharge is quite high for a LiFePo3 battery? Most people go to 25% or so.

"According to the Hubble AM-4’s specifications, we should get more than 6,000 charging cycles out of the battery at 50% DoD."

I think that's why the OP set it to 50%.

Which means the 2.75kWh battery is effectively a 1.3kWh battery. Running at 24-volts, expected to provide 230v with the occasional 1500w airfryer.

This article...I can't even. :ROFL:
