MPPT/DC to DC Charger for Trailer Build
Hello all, first time poster. I am currently doing a special purpose conversion of my enclosed gooseneck and am at the point to figure out electricity. I have a lot of 12V equipment, especially str...

Hi,
Two possible routes.
1. get a hybrid inverter charger. These allow for load support. That means power may be drawn from the battery bank to make up temporary shortfalls in power.
2. There are some inverter chargers that have 2 AC input sources.
A side question. Why do your dc strip lights draw so much power, and what are they being used to light up?
On my last trip I often only had 15 amp shore power with no access to the breaker panel. I set my hybrid inverter/charger to not draw more than 13 amps. When using the microwave I do see over 200 amps being drawn from the batteries.
Be aware that "load support" is not "voltage support". To have voltage support one needs an autoformer.
There's about 60m of RGB strip lighting (special design for aesthetic purposes) and from what I've calculated that is about 54a (60 led/m 5050 at 11W/m or 638w total). There's also exterior and underbody lighting which is about another 8a. Other items using 12V but not continuously are the awning (6a) and the powered vent (5a).
The generator is the shore power so getting 30a from that continuously shouldn't be an issue.
