Good Evening Y'all,
Long story as short as possible. I installed a complete solar system on my RV back in July 2020 and it has been working for the most part without any issues. However starting about a month ago I started receiving "Low Battery" alerts from the Inverter when we were running high draw appliances such as the microwave, electric fireplace or water heater (always just run one high draw appliance at a time). Also the DC lights in the RV flicker when a high draw appliance is running. In my current situation I only have access to 7A of shore power so we really rely on the 3000W Victron MultiPlus to provide power assist via stored energy in (4) 100Ah Battle Borns.
I called BB support and they directed me to disconnect the four batteries (which are connected in parallel) in order to check them with a volt meter. Three of the batteries were around 13.5 volts and one was at 0 volts. For the 0 volt battery I connected it to my truck battery to wake it up however after leaving it connected for over 15 minutes with the engine running its still shows 0 volts. BB Support said that the 0 volt battery would have to be RMA'ed. For the others they cautioned me if I did something to the batteries I would be charged a shipping fee and 180/hr for a BB technician to attempt to troubleshoot and repair. Also if I sent them in and there were no issues I would be responsible for hundreds of dollars in shipping fees.
What troubleshooting/checks can I perform on the three batteries to ensure that they are malfunctioning? The checks I've done so far is to charge all the three batteries up to 14.4 volts in order to balance the cells. Two of the batteries charged up to 14.3 volts and I connected them back in parallel but they are still showing the "low battery error". The third battery doesn't charge higher than 13.5 volts. I did purchase a Victron IP65 which I'm charging the batteries with as I wanted to remove the Multiplus from the equation just in case its the problem. I'm thinking about purchasing a load tester like this one to perform a load test on each battery: https://www.amazon.com/gp/product/B07V9W8SBD/ref=ewc_pr_img_3?smid=AZYZB6OQFMIQ6&psc=1
Any further guidance would be much appreciated.
