My existing system consists of 4.25 kW of panels, outback charge controller, Selectronic PS1 inverter charger, 48v 640 Ahr gel batteries, and 4kVa Lister generator. My current usage is about 6kW-hrs per day. I am located in western Vic, plenty of sun except for mid winter. I intend to change a few things and will increase my daily consumption. I am happy to remove all this (except the Lister), and want to increase to 8-10kW of panels. What is the best direction?
Enphase micro inverters, Fronius solar inverter, or Victron solar regulators, feeding into either Selectronic PS1 inverter charger, or Victron Quatro inverter charger?
I will change the ageing batteries to Lithium and keep the Lister.
I intend to mount the panels on a new ground frame as I don’t have an adequate unshaded roof. The panels will be about 50m from the existing battery/inverter/generator housing which I would like to maintain. I could mount batteries etc. alongside the panels, but prefer not to, and won’t shift the generator.
I realise this question raises a lot of other questions. But would like some suggestions that may clarify my planning before I look for any quotes. Suggestions on size of Fronius inverter and batteries would help if the daily demand was to double.
I hope you can help and don’t think this is to much like ‘similar topics’ which have read and found useful.
