I’ve got an inverter/shore charger combo and I’m trying to wrap my head around how to maximize solar usage from a separate mppt charger.
Obviously if my solar power is sufficient 24/7 I can simply leave the inverter/charger unplugged and rely only on solar to drive the inverter.
But when I plug the inverter/charger into shore power it immediately starts to charge the batteries at a minimum of 5 amps. That’s wasted energy if, for example, it’s close to sunrise.
On the flip side if the sun goes down, and the batteries are still near depleted, I may want the full 40 amps the charger can provide so I have backup for a power outage.
So how can I integrate these devices, preferably automatically, in order to maximize the use of solar rather than shore power?
