I don't mind if you irratate me, just be careful to not make yourself look dumb.

Without net metering, most of the newer electric meters used by the power companies will spin forward whether you import or export. The...

Yes, without an net metering agreement and all the needed approvals, they will be upset. You should either get an agreement or find...

If you put a volt meter at the battery and see 11v, you are seeing the battery's internal effective resistance causing this. If you put...

It would be helpful to know where exactly you are measuring the 11 volts. Is it at the battery terminals, the inverter input, or elsewhere.

99% of the time, this is loose connection(s), thin wires, or an improper bank configuration. 800W output microwave uses closer to 1300W...

My statement was "everything when determining fuse size or type for an inverter". That a far cry from everything. Ohms Law has a few...

The 400 amp fuse better be able to handle 600 amps for a short duration of time.

I believe what you mean is: ohms law doesn't account for everything when determing fuse size or type for an inverter. I totally agree. I...

The Question that was asked by the OP: Ohms law answers that question.

Don't compute fuse size based on surge current. Use max continuous current. Check fuse curve, likely 2x surge is good for minutes, vs...

Sorry, I was replying to Checkthisout. He did get one thing right. He frustrates me.

Ohms law also works on the surge current capacity. Anyone working on solar better at least know ohms law.

That formula is on the chart I referenced. Upper left middle of the pink area. You gave me the impression that you could do it without...

It's not my formula. It was developed by German physicist Georg Ohm in 1827. I'm sure the designers of those inverter specs you posted...

The questioner requested formulas. Could you please provide your formula? And do it as a function of manufacturer, model number and...

Since when did ohms law become obsolete? Wattage is a measure of power. Everyone knows that fuses should be sized higher than power...

I'm offgrid, solar powered. I use a Grundfos SQ-5 Soft-start 120V deep well pump. This is on a 120V/15A circuit with CGFI. Soft-start...

Formulas from Ohms law:

You know how it is. Your original intention was to see if this solar stuff actually works. So you pick up a solar panel or two and prop...
