What to do with excess energy?
#11
I'm in the same boat with summer approaching. There's always going to be more sun during the summer than winter and I will always have plenty of excess solar output. My water heater is natural gas, so during the winter it's 100% on gas. For the summer my plan is to install a pre-heater that's electric and set the temperature point at higher than the gas fired. I've already obtained a point of use 12 gallon heater that runs on 120V. That makes it easier to wire to my existing outlet, and will take about 800W, which leaves lots of room left for my 2.4kw inverter. The plumbing I'm hoping to be easy disconnect ('hoping' because its' quite rusty and I haven't changed the anode rod since purchase) and I have 24 inch flexible hoses to connect it. So it's either a 10 minute job... or... a nightmare...  Angel

Energy consumption also varies, no matter how large a battery is: it won’t charge any more when full. I find the sizing of these systems quite challenging.

Now I understand why Monty Python did not travel well... lol
If you can't quantify how much they cost, it's a deal, I'll buy 5 of them for 3 lumps of rocking horse ......
