6500w per hour?

Bill Ding Homes · Mar 31, 2023

So am i correct in assuming that with every hour of sunlight under perfect conditions i should be able to bank/use 6500 watts per hour using an all in one rated for 6500 watts. I dont know why this just popped into my head

That is your output watt rating for the inverter. It may not be the whole story if it is a split phase output because some of these add both 120v legs to get the total. It is not the solar panel rating, MPPT SCC rating or your battery capacity.

Not if you haven't got enough panels.

I meant if I did. I have 14k in panels for 2 inverters. Just making sure on my calculations.

Watts per hour isn't the right unit. I get what you're saying, but I think it's important to understand the units of measure. It's watts TIMES hours, watt-hours. One watt used for one hour. If you have 6500 watts of panels and a place to store energy, then at max, you could collect 6500 watt-hours per hour. Which is fundamentally different from watts per hour.

If you have 14kW of panels, then if you have a solar controller capable of that wattage, and sunlight perfectly aligned, you can gain 14kW of energy each hour…

Perhaps you could show your equation.

Kilowatt-hours of energy each hour.

Drop your location and array details into NREL's PV watts and you'll get a very good estimate the energy (kWh's) per month.

A good rule of thumb for a starting point for many locations in the US is: array size x 6 for longest days of summer or x 3 for the shortest days of winter.

6.5 x 6 = ~39 kWh
or
6.5 x 3 = ~19.5 kWh

6500w per hour?

Whatever you did, that's what you planned.
