[QUOTE="ReadiesCards, post: 444198, member: 28925"] Following on from: As I'm building offgrid I've gone heavy on the solar PV (30 Solarworld 285W installed on two roofs). As per the above question I've 5 of the panels connected to 3 charge controller/batteries/inverters powering various temporary circuits during the build. I'm wondering if I can use that concept in the final solution, so having a number of mid-power battery bank & inverters systems connected to a number of consumer control units rather than one big inverter and one big battery bank connected to one consumer control unit. So say the lights, downstairs ring mains, upstairs ring main, security cameras, fridge freezer are all totally independently powered (the circuit tails are all in place to do this). There are various reasons why I want to do this but firstly CAN it be done? While I can ensure a common earth for the inverters, I've no idea if the inverter AC sides need to be 'tied' or as long as I never connect anything from one circuit it will work without danger and if there are any specific precautions I must take.
