Hey Victron community,
We’re experiencing some issues with our solar setup in our van and would greatly appreciate any insights. Our system includes a Victron MPPT-100-50 solar charge controller and a Victron LYNX distributor 1000 DC, all integrated together. Additionally, we have a Renogy 2000W Pure Sine Wave Inverter Charger.
For the first two months, everything worked perfectly. Recently, however, our system has started acting up. The solar charging is behaving oddly. Instead of keeping the batteries topped up, it’s going into absorption and float modes when the battery is only at 60-70%, despite being in perfect sunlight. This issue seemed to start after the batteries reached 100% charge several times, which caused the Renogy inverter charger to emit a continuous beeping noise until we shut off the solar panels. We’re concerned that this might have caused some damage to our system.
Now, whenever we plug in a device with slightly higher wattage, the AC converter throws an error code 04 (low voltage) and starts beeping continuously. It won’t stop until we turn everything off and reset it, which takes a minute.
While we suspect the Renogy inverter charger might be part of the problem, we’re looking for advice primarily on how the Victron components might be interacting and if there’s something we’re missing in our setup.
Has anyone experienced similar issues or have any suggestions on what might be going wrong and how to fix it? If there’s any more information I can provide that might help us figure this out, please let me know.
Thanks in advance for any help!
