I have an Easysolar 24/3000/70 installed in my camper van. About 1500Wp of solar on the roof and a 24v 120Ah lithium battery pack.
The DC system of the van is 12v, with negative connected to chassis.
Should I connect the Easysolar ground to the chassis of the vehicle?
Should I connect the negative from the 24v DC system to the chassis of the vehicle?
Somehow I can't find a simple yes or no on these questions and there is no manual for the Easysolar (not so easy after all without a manual).
If yes to questions above, how should I connect it? Where in the Easysolar to connect the wire. What mm2 should I use?
