All, hoping for a bit of guidance on how best to make the most of my solar
My System Spec is:
5kWh Hybrid inverter
9.5kW Battery
7.2kWp Solar
During my Solar install we were able to fit an extra couple of panels on the roof so my Solar peak went up to a little ove 7kWp, compared to the 6kWp we orginally expected. As i have a mix of a SE aspect and SW aspect i thought this would be ok with some of the panels ramping down as the others were ramping up, but i’ve already seen multiple days well above 7kW .
The hybrid inverter obviously has the the ability to handle this but when the battery is full uit can only export a max of 5kW and its just dumping the excess as heat. I can offset this by dumping a little of the battery capacity before hand to make sure there’s some space, however once it reaches the lower limit it stops supporting the house, but this means that on cloudy days i’m just discharging the battery for no reason or drawing off the grid when the battery has the capacity and then charging it again later.
Is there any way to have the battery stay at around 80%, export everything else and then only charge the battery when there is a solar level above 5kW and then discharge back to 80%, whilst continuing to support the house?
You can set a timed export down to 80% say between 10:00 and 15:00.
This way if solar gen is lower the 5kWh then the battery will discharge bringing export up to 5kWh.
If solar gen is over 5kWh then the battery will take the excess as charge if space.
If the sun goes away for an extended period, the battery will stop exporting when it gets down to 80%.
It’s a good way to extend the max export, reduce clipping losses and fill in any lower than 5kWh dips.
Thanks, this is what I’m currently doing and it does stop the clipping as you describe, but when the discharge gets down to 80% it pauses all of the discharge, including supporting the house
It’s generally not that big of an issue, as most of the time when this happens there’s not a massive amount of usage in the house, but I have drawn off the grid a few times
Is there anyway to get it to keep supporting the house after the effort hit target?
