Following on from my dead BMS (Post here) I have bypassed the BMS temporarily to enable me to continue my trip. I've adjusted the charger inputs to 13.8v and am manually monitoring the cell voltages regularly.
However now I've got the battery working again I've noticed the solar output from my Kisae Abso DMT1250 is not sending any charge to the battery.
My system is:
310ah Lifepo4 4s
Daly 300a BMS
Abso DMT1250
415w bifacial panel - https://www.bimblesolar.com/solar/large-panels/LG-415W-bifacial-solar-J5?sort=p.price&order=ASC
3000w puresine inverter
Installed in a 2016 Renault Master motorhome
I installed the system several months ago without the solar panel and its been working fine charging from the vehicle battery. Last month I installed the solar and it worked great for weeks.
I'm now part way through a road trip in Europe and the solar charging has stopped working. The 1250 is still charging the house battery from the vehicle battery fine when the engine is running but in full sun with no shading the 1250 shows 48v output from the panel on ch2 but 0.0a charge output to the battery.
All connections seem secure.
There is no visible damage to the panel.
The battery is at 60% state of charge, 13.2v.
What am I missing here?
Starting to wonder if the Mppt charger in the 1250 did something odd and fried itself and the BMS?
