Hi everyone. Working my way through soldering my 2500 cells into 100p blocks (around 20kwh) so taking a breather, and fresh air break to get advice on next big purchase which will be the solar panels and the mppt controller.

Recently had 5kWh of panels installed with a fronius hybrid inverter but the contract I have with a local generator means I can't connect any batteries to it for two years! Should have read the fine print but the total install was half price and is working well. So not wanting to waste all the 18650/harvesting and learning I have decided to install more panels and a solar panel hybrid converter to supply the batteries.

Ultimately I want to connect them all together but for now I need some advice on best inverter \ controller that will interface with New solar panels and battery bank, store the energy during the day and allow me to use the battery storage at night.

As always, thanks guys for the help

Paul
