Hi folks.
I browsed around the forum but never registered, today I made the effort. We have had my PV system for around 18 months, extremely happy with it so far.. In that time we added a couple more batteries (4 to 6) and upgraded our EV charger to the Zappi to use lower energy levels.
Only issues we had were in the coldest winter nights when the batteries/invertor detected too low temperatures and we didn't get the off peak charge session. I customised some server cabinets with thermostatic controlled heating and cooling and that fixed it for all seasons. Happy to share details if anyone is interested.
