Hi all, just new to the Forum. I've recently purchased a couple of these ATS units for upcoming projects.
I'm wanting to incorporate fully automatic AC and DC charging, not just automatic transfer of the 240V AC load supply in my systems. I'm planning on using a typical MPPT to charge 24V LifePo4 packs to run the inverter and so on. Since the MPPT is taking care of the solar charging duties, I'd like the ATS to switch on an AC/DC charger when grid connected to take over charging when the sun isn't shining, to help recover the batteries quicker, or I am better off just waiting for the sun to do it's thing instead?
Does anybody see an issue with connecting the AC/DC charger on the 240V output of the ATS (which would be also connected to the inverter output/AC load circuit)? Only potential issue I can see unless I'm missing something, is when the ATS switches back to battery power, the charger output would essentially cycle back around via the batteries and inverter, powering itself and inefficiently waste energy instead of peak charging the batteries.
In this case, it would make sense to only power the AC/DC charger when using grid power, so how would I go about doing this automatically? Of course there are Hybrid inverters that take care of the whole thing, but I'm exploring how to do it with this ATS.
Thanks all.
