Does anyone know of a Columb counter preferably with wifi that can reset to 100% at a set pack or cell voltage ? The problem being columb counters drift upwards due to the bms doing its active balancing of cells.

I recall when back when I bough a Lithium battery that it came with one of these PZEM-015 battery monitors, if my memory serves me right the "Capacity Ah" went up when charging and down when dis-charging thus giving an indication of the number of Ah left in the battery. The battery monitor...

Can anyone tell me where to connect this cable to, connection block highlighted in red ?

Had an off-grid system for several years now with no connection to the grid. As of 10th January the inverter ( a Sorotec REVO VM II ) no longer shows the PV Voltage / Amps / Input on its display yet it continues to charge the battery although to a lesser extent about 60% of normal. The PV...

I have gone with 4x 48v https://powmr.com/products/mppt-solar-charge-controller-60amp-12v-24v-36v-48v Will set the charge voltage on one unit slightly higher than the others.

I am aware that multiple Victron MPPT solar charge controlleres can be connected ( in parallel ) to the same battery bank. I approached a budget manufacturer POWMr and asked them if multiples of their MPPT charge controllers can be connected to the same battery bank and they replied "Parallel...

I have 2x 48v 10kw lifpo4 batteries, coming back from 2 months away, I found that all of the cells from one of the batteris have swollen and not by a little bit. Looking at the logs it appears the mppt charger at one stage was charging 62v and then died, why the BMS did not intervene ? I have...

I have a 48v 10kw LiFePo4 battery, I want to add another 20kw, am I better to add 2x 10kw batteries or am I ok to add 1x 20kw battery ? The reason I ask is that manufacturers move on in producing larger battery cells, I bought these 200ah cells a year a go and now they say they don't sell them...

I am finding that the passive balancer in the BMS is draining of overly charged cells, and this cell drainage is not being fed back into the shunt, therefore the shut gives every increasing battery amp hours with each charge. Anyone else come across this, any workaround ?

what are your settings for working mode bulk charge V float charge V

Support email address support@soroups.com they are responsive.

I bought a number replacement control boards instead about $50 each, that come with teh firmware pre-loaded, and swapped them out into each inverter. For this I went direct to Sorotech.

My boats DC electrical is 24V nominal and I'm planning to install a 40kWh battery bank. The battery supplier ( China black box with built in BMS ) has dis-couraged me from connecting any more than 2 batteries in parallel. I have been using their batteries ( 2 in parallel ) for years in my land...

My boat is a salvaged boat, it had sank, all the electrics has to be replaced, and I paid cash. I hadn't considered approaching a surveyor but I do agree that would be the first step if I were going to insure the boat which as yet I am undecided. Currently I am considering soley the safety...

It makes the installation easier to use High DC voltage strings..... An example where shading is less of an issue, however the installation is still to avoid strings of high voltage dc and parallel panels to several mppts.
