Hi all,
I'm upgrading the system on my motorhome as the current inherited system is old and not very effective (120w single panel with 20A cheapo nastio controller and 100Ah batteries)
After lots of reading and weighing up the pros/cons, I've gone with (and already purchased):
6 x 100w mono panels, in series (total max Voc of 129.6V and Isc of 6.11A)
2 x 180Ah AGM batteries in parallel (I'm waiting on specification data from supplier for parameters)
Epever Tracer 6415AN 60 Amp controller
Epever MT50 Monitor
1000w PSW inverter
4mm2 solar cable - from array to controller
So my questions are:
1. As the array will be in series with Current remaining constant @6.11A am ok with a 10A breaker between the array and the controller?
2. What kind of current would I expect from the controller to the batteries (to determine cable size).
3. Considering question #2, what size rated breaker and fuse would I need between the batteries and controller?
4. I was intending to join the two batteries in parallel with 25mm2 links. Is this size sufficient?
5. Because of the parallel configuration of batteries being 12V/360Ah, in the Epever parameter settings, do I set the battery size as 360Ah or 180Ah. I've read that I'll need to set it up under 'User' settings as it won't recognise an AGM.
Thank you!
