I have read the threads re setting up a system using battery storage. Is it possible to set up a system using an old house 3kw system direct to 240v power outlets or does excess power gave to go to mains. What I am looking at is just running pool pumps. I am not bothered about storage in batteries to use at night, just running the pumps while the inverter produces power during the day. Can Iget set up and just run power direct to the relevant power points without having mains back up. I know I can add batteries later but dont have the need at this stage. Maybe tool battery chargers that are 240v only. Would be on timer so only run during the day.
