Yes, at the same time. But the houses are not connected in any way, electricity or water.

Hi all, I have quite a strange problem. My house is 100% off grid with no Eskom connection. 8kW Sunsynk inverter, 4 x UP5000 Pylontech batteries and 12 x 550W panels. Often when it starts to rain softly the earth leakage on the DB trips. No other CB trip and no error codes on the inverter. I can switch off all the CBs but the Earth Leakage can't be switched on. After about 10 mins I can switch on the EL, and the problem disappears, even if it carries on raining. Funny thing is it happens at the same time with my neighbour, with a similar installation. Any ideas would be appreciated. Thanks

Hi all, On a Victron BMV, should the 100% SOC be on float or bulk charging Voltage? I have 2 x Huawei ESM48100A1 batteries and the bulk is 53.4 and float 51V.

I got mine from ICC directly, it is their product isn't it, and I'm very happy with it. Setup with emoncms and True VNC was easy and Manie from ICC was very helpful. He even logged into my VNC twice after hours to help me set up. Emoncms costs 1$ per feed per year, so its nothing. Seems to me like Sammy works for centurion solar...

Thanks Jaco, will rectify!

It seems to be the BMV itself, I have the 712 and the SOC on the BMV shows the same discrepancies. If the shunt is reversed could this cause the problem?

Here is a good example, clearly cant be at 100% after the discharge of the last 2hrs.

Yes but the soc is clearly wrong most of the time. ie I would have discharged about 3kwh from the batteries and the soc would show 95%, or they would be almost fully charged and it would show 50%. No idea anymore

That is the one Im getting thanks

@Coulomb I have a BMV 712 installed but I'm struggling to get an accurate soc reading. Currently its as per attachment, should be around 90% I reckon. Also soc sometimes show 40% when its on 51V???

Thanks!

I'm sure this has been covered somewhere but I can't find it. Is it safe to put a 100L geyser with a 2kW element on a 16A Sonoff switch? What would the surge power be for this element?

Thanks GVC, which batteries do you have? Whats your float and back to batteries V?

I also lowered back to grid V to 48 but I kept getting low Voltage alarms from the inverter
