Warning- serious Newbie. I have a 2018 220RK. I purchased the Victron BMV-712 battery monitor and hubby took a stab at install using the included instructions, apparently not very successfully. We charged both batteries to full on the battery charger prior to the install so I could do the setup. I went on a week long boondock. Somehow we managed to hook it up so the batteries were not charging on the generator like I thought. I didn't see any change on solar but it wasn't ideal conditions so I didn't think anything of it. During my camping trip, I had a false sense of security when I periodically checked my app it said my batteries were between 80 and 100%. One evening in the middle of my stay the lights dimmed and the refrigerator looked like a disco with the lights blinking. I shut it off thinking maybe my propane was low. I checked the tank and it still showed green and the stove lit just fine. The refrigerator wouldn't power up on gas after I turned it back on, so I knew I definitely I had a big problem. I powered up the generator and fortunately, the refrigerator ran fine on AC so it wasn’t lifeless. I thought maybe I had a corroded battery post with a bad connection, so we cleaned them all and hooked it back up. Wasn’t that. Finally tested them and both batteries tested fully discharged. We tried charging the batteries with a regular battery charger, but as a result of the discharge, both batteries are toast and they won't hold a charge for long. Looks like I will be replacing both. Before I do that I am looking for specific installation instructions for the battery monitor to get everything hooked back up correctly so I don't fry the new batteries too. Not enough knowledge to feel comfortable messing with it again on my own since the first time was a big fat fail. I’m fearful to mess anything up any further by wiring it up wrong again and doing damage to something. Clearly, an electrician I’m not, and all of those wires in the front compartment are overwhelming. I can't find any videos online that show step by step where all the wires go, likely because there are so many variables from rig to rig. I have been searching to find specific wiring instructions but haven’t found anything but general overviews of completed installs. I did see some nice set ups and I do like the bus bar idea that I saw on one video as that seems to organize and alleviate so many connections on the shunt post.
Any suggestions where I can find a "BMV-712 battery monitor wiring for dummies on a 220RK" or a mentor that can walk me through this?
