Jadeshay Grid Tie Inverter 1000W MPPT Micro Inverter Solar Inverter for Solar PV Panels Adjustable Battery Discharge 24V to AC220V

I purchased this grid tie inverter because my Y&H 1000W discharged the batteries too far and some of my lead acid batteries in my solar installation gave up (after 6 years to be fair). I got an undervoltage protector and a Solid State relay to add to the Y&H but I thought it would be nice to have that functionality in the inverter itself. Indeed that is the component that for me has been missing from cheap solar installations from the start. But finally Jadeshay has stepped up and solved the probem. You can adjust the cut off voltage and the restart voltage. But that is not the best thing about this device. The best thing is that you can program the max power output to equal your average electiricy consumption. then you will not be feeding much back to the grid and instead will use all the power you generate to reduce your electricity bill.So instead of firing 500W at house house and 1kW at the grid for the 4 hours of sunshine we are lucky to get in this sceptred isle. You can fire 500W at your house for 12 hours. It is a game changer.Be sure to set the damn thing to battery mode not PV mode or it will just cycle between 0W and 1000W output and then stop every minute. The Display is useful if a bit video gameyfied.
