What are solar AC and DC disconnects and why do you need them?

An AC (alternating current) disconnect separates the inverter from the electrical grid. In a solar PV system it''s usually mounted to the wall between the inverter and utility meter, and can be a standalone switch or a breaker on a service panel. DC (direct current) disconnects are switches that can interrupt the flow of DC.

6. Controlling depth of discharge

If the battery SoC falls below the SoC low-limit for more than 24 hours, it will be slow-charged (from an AC source) until the lower limit has been reached again. The dynamic low-limit is an indication of how much surplus PV power we expect during the day; a low-limit indicates we expect a lot of PV power available to charge the battery and that the system is not expected to
