    Re: Generator fuel consumption?

    These figures seem to be spot on. The 100kVA should use a little bit less under the same load but when estimating one can use just below double for the 100kVA. About 5% less.

    Although the genny should power the element bear in mind the 2500W is at normal temp. When cold it will draw quite a bit more power. Resistance does increase and lower current when hot. Not as bad as...

    You are lucky for the good yield on Sunday. Saturday I got the same as my previous best but Sunday was down 22% from Saturday yield.

    For a while I have been using lithiums with my lead acid. Working real good.

    Re: New building - what geyser options

    Without making it a debate. The heat pump would use like 1.5kW from the grid to produce 4 7kW of heat. So the same formula cannot be used.

    Re: G1000/Jackery 500/1000

    At 300Wh you can use 150W load on 220V for 2 hours. The 80Ah measure will be the size of the lithium batteries. As indicated AC charging and solar will take 6.5hrs.
