As I start to design my “perfect†p v system, I find that planning for panel output vs. storage vs. the best use of a dump load is kind of like trying to put together a jigsaw puzzle made of jello.
For now, I'm trying to firm up my knowledge of dump loads, and I'd be grateful to anyone willing to share what has worked for him or her.
I currently have an electric water heater, so water heating (preheating) is one obvious candidate. I don't like the idea of running a water heater off the main system inverter, and think a cheap inverter and transformer ( if there are such things ) could work to produce the sloppy 120 or 240v needed for a resistive load.
Of course, putting the raw excess d.c coming off the panels would be even better.
Any thoughts on doing something like this, OR other dump loads would be greatly appreciated.
