I thought I'dmake astart to document my efforts of a Power[on a bench]wall type thing.. so here it is
.
Currently we have 3.2kW of solar on a feed in tariff whichI'm not going to mess with so I'll beAC charging from that and ten 12W/12V panels (used for charging atm)which I'll probablyreplace in the future.
I'll also own up to being a cheat as I'm using 12.8v LiFePO4batteries rather than the precious 18650 and the whole thing willhopefullybe a feeder for more projects (battery monitors/chargers/etc.) over the next few months/years as the addiction catches hold.
At the moment I have five 12.8v 100AhLiFePO4batteries (~6.4kWh) in series connected to aGTIL-2000 on the workbench whilst testing/I work out their long term home https://speedtest.vet/ https://vidmate.bid/.
Mains power to the [isolated] 20Achargersand GTIL-2000 iscontrolled by a couple of Energenie 4-ways and to get things started I have the batteriescabled up toa resistor divider on top of an Arduino plugged into aRaspberry Pito keep tabs on the voltages which also has the Energenie transmitters connected.
