Solar Electricity: Issues with an MPP 10KW hybrid inverter
Basically what the issue is:
It takes power from the battery when the solar panels does not input any power what so ever. It should use the grid.
If i have 20w pv input it charges battery with 20w. If I have 0w PV input it then starts using 120+watt from the batteries.
I have set the inverter to not use batteries unless its needed. Note that the inverter shows that 0amp is taken from the batteri. I think this is an software issue that should be corrected. Because if im using grid for everything it should power the inverter from the grid and not the battery. By doing that your/mine batteries will last longer!
I quickly show how i went and build myself an switch where i can switch between grid source and the solar/inverter source for my servers in the house.
I did this because if and when i do maintenance i easily want to be able to switch it to grid if i take down the inverter. This can of course be automatic aswell if inverter dies it switches over.
Thats another video that will come!!

Lightning killed charger for my lawnmower and one of my meters to my solar system.. SAD day :( 350EUR loss
-- More information below! --
No I was not at home when it happened and the neighbor said it was direct hit. It had taken out some things at his house too :)
Never the less. I just wanted to show you guys whats going on :)
And i couldnt bother repairing it. I did not have much time over to spend on it so i ordered a new one. I hope insurance will cover some of the cost... :(
As of as I undestand right now they will cover 2/3rd of the cost so getting new AC-DC and then trying to repair would have been same cost. Except waiting for parts.
Due to its ebing 34VDC and 4A its a bit of special AC/DC

My system as is today controlling the heat to my house.
It utilizes DS18B20 sensors and can decide if its going to send more heat in or not based on either outside temperature or inside temperature.
