Hi, I am considering to build a third battery and have decided to go for a vertical battery-box. I would like to buy the box without a BMS and install a BMS that I will buy separately. Prices of the boxes are similar, but the design is slightly different. Shipping seems pretty fast for...

I would like to add one or more victron SCC to my system. Sick of getting error 55 on one of my MPP-Solar AIOs. They idea is to keep the MPP Solar inverters as is, but disconnect the PV power and have that managed via an additional SCC. Looking at different options from Victron and came...

Hi all, I have ordered two new solar charge controllers. The MPP Solar All In Ones will only be used for inverting. In the current setup I have added two Class T fuses (one per inverter). With the addion of the new SCC's I assume, I need to fuse the lines to the SCC's as well. Do I need to...

Hi all, I have not posted much on the forum, but have been reading a lot, learning a lot and now have decided to build a new Lifepo4 battery as a replacement for an AGM battery bank. Most of the parts are on their way, but expect everything to be here by the end of March. Since I live on the...

Hi all, I searched the forum, but could not find an answer wrt to this question. If a bms (in this case an overkill/jbd) disconnects because of an overload, how and when does it reconnect? Assuming that the inverter draws over 100 amps, the bms will disconnect due to an overload. After...

Hi, I would like to 3D print a plate that holds the communication board of a new JK BMS. This board is identical to the boards used by Globel Power and Pace. Searched online and already reached out to manufacturer in order to get the exact dimentions to be used. Is there anyone in this...

Just installed my first new build and observing it daily the last week. I have plenty of sun here, so the battery gets fully charged every day. I consume approx. 30% in the nights. Looking at the underneath curve, i am wondering if it is healthy for the battery to get fully charged daily and...

Usually I don't discharge my batteries very low and have very conservative settings. Back to grid at 50v and BMS discharge-cutoff at 2.7v (lowest cell). Since solar is not fantastic these months and guests are arriving I do expect that my current setup will not be able to supply enough...

Hi, I would like to isolate my inverter from AC-in, and only allow AC-in if that is neccesary. The reasons why I want this are: 1) the inverters that I use, use AC power if connected to the grid. If disconnected they use from the battery/solar 2) we have a very instable grid and after outages...

I would like to program and use the dry contacts in my new JK-inverter BMS. The purpose of this is to control a relay that switches AC-power-in to the inverter to 'ON' if the battery gets below a certain SOC. That way the inverter is disconnected most of the time from the grid and only has...

Hi all, Yesterday I added a second bank to my system with a JK BMS. One bank is running for 60 days now and hooked up to Solar Assistant. I tried to add the second bms to SA as well. I was able to add that one (used a USB hub), but after connecting it gave a connection error. Was able to add...
