We have used over 140 of these units, mostly the 5KWH.
They are solid and really well performing batteries. Love the 1.5C

AndrewO reacted to Pieter Lourens in 150pv water heating systemHi @AndrewO
I have two geysers using the same PTC elements, but without the the MPPT tracker. Please note that GeyserWise components are advertised with contradicting specifications. I found that you can push the voltage above 72V, in the region of 90V if I remember correctly. As such you should be able to put all three panels in series as advised by this forum. However, ask GeyserWise themselves and they will advise.

AndrewO reacted to Scorp007 in 150pv water heating systemEvery panel will give over 36V and you don't want a single one to give over 36V. You can also not connect any 2 to be at 72V. Also you cannot connect 3 in series not to run the risk of going over 150V on cold days. So it seems 2 in series of any of these. Then add more strings in parallel to increase the current.
