Hi, I had a H1 Hybrid Inverter fitted as part of my solar panel install. I want to add my own batteries. I've seen a CM4300 for a good price, will it fit or is it now obsolete? Should I stick with ECM/ECS batteries

You would need to know the version and connector type on the CM4100 to be sure which is a bit of a minefield, You will also need a minimum of 1 master and 1 slave. I would say it was better to stick with ECM/ECS (V2), EQ or EPxx batteries - they are all readily available and upgradeable later if you choose to.
