Hi there,
I got a Victron 305W Solar panel and smart solar MPPT 100/30 installed by a mechanic in my van but I feel like it's not working appropriately.
The Mppt is connected directly to the batteries (2x100Amp in series) (positive on first battery, negative on second). Theres a fuse breaker between mppt and batteries.
My problem is that the app always shows float, no matter how much I've used my fridge, lights etc. It also shows immediately whatever voltage I put in the battery settings. So If I change the battery voltage to 14.0 it just jumps to it without ever entering "bulk" mode. Lastly my wall voltmeter (I know it's not fully accurate) keeps dropping during the day and night.
Not sure if it's important but I also have a split charge relay to charge the batteries while running the engine. So when I drive for a while and stop my wall voltmeter shows 12.8V while the victron app doesn't show a higher voltage. When the engine is running the app is jumping all over the place showing battery voltages between 4 and 15 and going between float, bulk and absorption.
I would really appreciate any help.
Thank you in advance.
