i got a off-grid system i build but got to the point i need a bit of info.
Got a equivalent to 560watt of solar panels and might expand on that soon, on a 100/20 mmpt charging a 100A/24v lithium batteries pack.
Phoenix 1200/24v inverter in use for inhouse , tv , pc or other.
This setup been going good for a year but because of not wanting to risk of damaging the batteries i always only had it to deliver power in evenings and nights.
The reason is because i struggle with this:
When under load the voltage drops a good part, like from 28V to 26.5v for example.
Now i worry that if the panels during peak give more power then what im pulling from the batteries , the batteries would still be full but because of the lower volt the regulator would try charge them anyway and overcharge the batteries right?
