I wanted to put our r290 gshp near a kitchen drain. And found to my dismay that it didn’t have a trap! Bit of a faff, but managed to swap it out for...
@ggw When the sunsynk is used in lithium % mode, it also still makes use of the basic voltage figures from the lead acid mode - these must be set corr...
@ggw I left ours in AGM volts mode for maybe 2 months, the adaption was automatic but slow. I did try and hurry it along by manually tweaking the A...
We have 304Ah batts too, but after letting the sunsynk auto detect to the size, it thinks they are vastly different to this. Our system now works ver...
When we first installed our Sunsynk I initially tried to use Li-bms as the battery state - this was dreadful, resulting in all sorts of weird behaviou...
@ggw I had a lot of trouble with the sunsynk originally(ok, I still do…). New LiFePo4 battery, with the Seplos bms that talked with it, and yet I fou...

@misterb I'd originally intended to top balance in parallel. When I thought it through, it just seemed a lot of faff - how to compress the cells? ...
@misterb Yes. In the case, compressed, with a capacitive active balancer. I think balancing should not be done uncompressed.
We charged our 15.5kWh 280L system to 56V in AGM V mode (3.5V per cell) over the coldest months with Octopus Go, which is 100% or near enough. That w...
@ggw I think the cable to the unit needs to be double insulated if you can touch it. Ideally the twisted pair from the CT should be away from any ma...
