So next year ill be ditching the old 12v setup in favour of GT panels and 24volts!
Here is my proposed system. Blanks filled in and advice is mutely appreciated!
4 x Panasonic panels - HIT VBHN285SJ40 - 285w
ISC - 5.91A
VOC - 63.5V
IMP - 5.49A
VMP - 52V
One of the panels is actually a VBHN295SJ46 295w @ VMP - 52.7 V. IMP - 5.6A and VOC 63.7 V but I'm sure these readings are so small not to have any type of negative effect?
They will feed to an MPPT Controller - do i go with a Morningstar MPPT 45 or a 60?
Or an Outback Flexmax 60 or 80?
Batteries - Im not decided on this - thinking - USL16 U.S. Deep Cycle Battery 6V 380Ah or Rolls S-290 or Rolls S-330?
This system will be to power LED lighting - around 13 LED's at 5w a couple of hours a day.
Constant 24v fridge.
24v Television - Again few hours on an evening.
1000w Inverter/Charger - Victron maybe? Connected to backup genny for occasional charging of batteries. Not sure how these inverter/chargers are linked into the system and do i need to isolate panels/controllers/batteries when I charge from the generator?
Any advice on the above is greatly welcomed and also advice on cable sizes, breakers/fuses (if needed) or any other safety devices?
