Hello,
My campervan is almost finished but the Renogy system is still not working. I contact two campervan specialists (I payed them more than 1000 euro already) and I purchaed for a couple off thousand Renogy stuff. So you are asking me if I m satisfied? No not at all. So I hope you can help me ?
We bought this:
- 5 renogy solar panels (see correspondence benead, and atachemend)
The specialist (B & S in Hoorn, builds a lot of campers with Victron stuff) has checked the installation: everything seems to be connected properly. There is also little to no power leakage (same as they install it).
He only wonders whether the solar panels can be connected in this way (1 strand of 3 and 1 of 2). Are you sure this is possible as you confirm below?
If so, does it not charge on the solar panels? (Not even with other batteries, 40 volts but almost no ampere also on a sunny day, is 40 volts logical? ).
The bms doesn't seem stabel.
Regards,
Jules
How can we solve this?

What happens?
After installing on May 21, the battery was at 80%. .25-05 on 76% What was striking is that it does not really charge on the solar panels (see the photos of the BT app). I then plugged in a vacuum cleaner and then it went to 66%. 26-05 he was suddenly at 4% percent and within an hour at 0%. (How can he go from 66% to 0% in less than 24 hours without anything heavy on? Same evening 2 hours on the charger and was back at 87% in the evening (how can he go from 0 to 87% in less than 2 hours?) Next morning at 78% (10% less without actually turning on). This morning he got up at 60% shortly after that he went to 0 and overdischarched although it didn't turn on. drove another specialist where I already had an appointment, then briefly turned on the engine and suddenly it got back to 76%.The specialist (B & S in Hoorn, builds a lot of campers with Victron stuff) has checked the installation: everything seems to be connected properly.
