Hello, I'll be upgrading my inverter and I'll need a bigger circuit breakers between the batteries and the inverter(s). I currently have Schneider Electric breakers and could not find bigger than 63A breakers of the same brand locally. I would need at least 125A or 150A 2 pole breakers and I...

It's been like two weeks of rainy days with very little sun but today its been finally a sunny day (so far). Today's solar harvesting until noon has been about twice that of previous days for the whole day. Hopefully my batteries get a full charge today.

Hello, I'm considering the idea of changing the batteries of my server/network rack with a LFP battery. I know LFP does not like being at 100% charge for long periods is time as it degrades them. Since an UPS cannot detect SOC, would it be possible to limit SOC using voltage? What charge...

Hello, I would like to know if there's a tutorial on how to read data from a Morningstar TS-MPPT charge controller and and log the data in a plain text file or send it to something like InfluxDB. MS View can get data in real time, so it must be possible to do it another way. I would like to...

Hello everyone! I got 5 LG EM048126P3BA 6.5KWh 48V modules for really cheap. They all work but I have no way to communicate with the onboard BMS to check cell voltages and balance them if needed. Because of this I decided to get a new BMS and my choice was the JK BMS JK-BD6A17S8P as the max...

I found this app on Fdoid called SolXpect to get a forecast of solar harvest. I entered my location and solar panel data and went to forecast. It showed 14KWh for today, which I didn't believe as it's been cloudy lately but to my surprise the charge controller showed 13.97Wh which is pretty...

Hello to all, new to this forum. In late 2019 I decided to install a solar energy system for my home due to a difficult political situation in my country and the threat of long blackouts of the power grid. Besides, the energy costs here are absurdly high, so saving on the energy bill was also a...

I'm evaluating buying a couple of Multiplus II 48/3000 for split phase use. I'm a bit confused about the real output of these, as the spec sheets says one thing but the "Technical notes on output rating, operating temperature and efficiency" document says something else if I understand...

I just installed two Multiplus II 48/3000 in split phase configuration. Split phase setup went smootly with the Victron Connect program but it defaults to being in pass-trough mode. Tinkerin with the VE Config program I tried the "dedicated ignore AC input" VS but it only works for L1 when an...

Hello, I had an array of 9x330W panels on one TS-MPPT-60 and I originally planned on maxing out the controller and putting new panels on another TS-MPPT-60 I had. The panels I originally wanted to purchase were not available anymore when I had the money to buy them, so I had to settle for that...

Hello, I recently installed two Multiplus II 48/3000/35/50 in split phase configuration and I've been finalizing details here and there. I was watching the consumption reported by the inverters and it seemed a little off to me compared to the APC SUA3000 I was using before as an inverter. I had...

I'm considering using small LiFePo4 batteries to replace VRLA batteries in a UPS. I've searched about this but I can only find info about max charging or float voltages, but nothing about proper voltage for long standby use. From what I know lithium batteries don't like sitting at 100% or too...
