Hi guys,
I'm trying to piece together a off grid solar system and have some questions so far I have:
I have 10 x 345W solar panels.
Spec:
Am I correct in thinking I multiply the VOC by number of panels - i.e. 410 VOC requirement for the inverter requirement - so an inverter with 450 VDC would be sufficient to run these pannels?
-I Also have a lifePo4 battery on its way - 48v.
I wanted to get the GroWatt SPF 5000 ES inverter as it looks perfect however unable to find any suppliers in UK - only China, dont want to buy as I can see some peoples feedback where unit has failed and no responses etc. anyone know where I can source in UK or EU?
....Alternatively I found this other 5k inverter with similar specs:
"Maximum PV Array Open Circuit Voltag : 450 VDC" - so this would run the above panels as they come to 410 VOC total?
-What is floating charge voltage? 54v - is this max battery voltage the unit will take?
- Any advice on how should I arrange my panel string - parallel or series ?
- I think this would work with my lifepo4 48v without issue.
- If this sun is shining and power is being produced, will my load draw power directly from the panels - before using the battery? or everything is drawn from battery regardless
- any other recommended inverters (sub £1000).
Thanks guys!!
