Connecting to the 'Load' Terminal

Postby NorthEGPhoto » Tue Jul 03, 2018 1:20 pm

Pretty much any solar charge controller has a 'load' terminal on it. It seems people don't advise connecting anything other than minor loads like lighting to it. What is everyone's experience?

Reason I ask is - I have a nice MPPT controller rated for 30A. it has a bunch of charge state and load displays which aren't useful unless the load is attached to that. I'm just concerned I'd be putting my DC/AC on that single point of failure and possibly euchring my charge controller as well if it fails.

Thoughts?

Good SCs have good load circuits, but are usually limited low current.

Crappy SCs ones only work with resistive loads.

I prefer setpoint adjustable LVDs, divide up circuits by current level and how essential.

So the screens cut out long before the fridge, but safety / navigation gear keeps going until 15% or 40% SoC, depending on bank chemistry.
