@muddymuddymuddmann The EV motorcycle charges at the same rate whether it's from solar or grid. It's pretty much just a trickle charger on there. I want a fast charger for it, but it just hasn't been a priority.
With solar panels charging a battery bank, that allows charging of an electric vehicle at any time, day or night. You can also charge at a higher rate and different voltage than the solar panels would provide by themselves.
Thats a great home brew system. I couldn't tell for sure what sized battery cables you have but they should be 2/0 as if/when that inverter really draws you will melt the smaller wire. I have two of the ElecTraks although one has the transmission almost done for. It is almost 40 years old.

My battery wiring is a little thin. I plan to replace it with something thicker once I get this all worked out. I have only been running pretty light loads on it right now. It's a 48V system, so I can use thinner wire than a 12V system would.
My electric car has 2/0 cabling, and you can put hundreds of amps through that.
On a 48v system, it's essentially half the voltage/double the amperage of a 120VAC system. I should use wire twice as thick as a 20amp AC system
@rlewis1946 The batteries are simply store brand group 24 flooded lead acid 12V deep cycle batteries. These are what you could get at any farm/fleet store.
So far, the only maintenance on the batteries was topping them off with distilled water right after I got them. The mower is designed to work with flooded batteries and allows for gassing/venting. Nothing in the mower seals up. Where the back seat and hood go over the body, there's almost a 1" gap all the way around to allow for air flow.
I spent $200 for the used electric riding lawn mower. All the batteries in it were salvaged (free). The UPS is worth about $2000 new, I got it as salvage from a friend who works in the computer recycling industry. I already had the other batteries that were in the rack.
I would have been buying the other solar components anyways.
So, for a couple hundred bucks, I have a lawn mower that needs no gas, no oil changes, makes NO POLLUTION, and is quieter than the neighbors nower.
Luv it man! Will be in further contact, I'm a new fan :)

Yes, you did. I have a couple old TV studio scoops around. They make great work lights and winter heaters....

BEN, SWEEET JOB. I LOVE IT. TAKE CARE OF THE BIKE. I LOVE THAT THING. HOW LONG DOES IT TAKE TO CHARGE THE BIKE OFF THE SOLAR?

thats a heck of an inverter/battery arrangement for just 1 panel, but yes it has a lot of extra potential

I have 7 more panels that I can connect to this system. The charge controller, batteries, and inverter can handle all that.
I wish I had better solar access at my house! I think these may end up on a pole mount in the front yard.
48V (or higher!) is much better for longer cable runs.

@BenjaminNelson I am using 67 loaded-90v open circuit panels. Take a look and the vids I have on the "umbrellas" I use.

Thanks for the update! What brand are you batteries and can you tell us about your maintenance process on them. Keep up the good work!! RL

But for all the cash you forked out for all of that equipment you could have just bought a brand new lawnmower and all the gas for it, couldn't you?

@BenjaminNelson Hey man, im all for it as long as it saves money, I was just wondering. I would love to be off the grid

That is AMAZING! Oh, and I TOTALLY smiled and waved back [IRL] when I saw your reflection wave in the solar panel.
