I'm looking for a solar kit that can output at least 1500 watts in full sun with the ability to plug in AC devices. My plan is to run two pressure pumps during the daytime to irrigate the lawn and gardens with a sprinkler system from a nearby dam. I know about the dedicated solar pumps you can buy but I was wanting something more versatile so it can be used for more than just pumping water if I ever decide to hook up fans or small air conditioner. Can it be done?
Solar Setup without Batteries?

I thought they didn't work without the battery? Do sell any kits with just the panels and outlets?
Only supports max 200w panels and is not designed to drive a pump.
Buying this for OP's needs would be a terrible idea.
No need to be so judgemental
You're a spanner..
Might be worth checking in with springers solar. They are at Lawnton in brisbanes north though.
Just get a 6.6kw system installed.

You wouldn't want to run AC/heaters at night? And if not you, then your SO/kids, or your future potential SO?
For irrigation from your dam, I did the following
Purchased some old second hand roof top panels (8 * 190 watt), cost me $200, then I purchased a solar pump from here: https://www.wbspump.com/ .
They have integrated solar controller so you just plug the panels into the controller, drop the pump in the water and you have LOTS of water pumping!
They will match a controller & pump system to match your panel specs.
I've had my system running for 3 years now with no issues. My dam is 200m from my header tank and 60m vertical lift - this setup pumps thousands of litres per hour.
Then just get a standard 6.6kw rooftop system for your house power - do not waste money on a smaller system.
Hey Idroid, 8 panels are 40v = 320volts. So you need to factors some cost for a sparky to do the wiring.
Plus you need to mount the panels at an optimum angle, which would cost something for the mounting..
surely it would be easier to run a 240v extension lead from the house ?

It's standalone and not grid connected - no sparky required.

Sorta true - I just made a ad hoc stand out of some scrap metal (old pallet rack) - cost was only my time. But even buying a stand is not prohibitively expensive/

In my case - 200 meters of exposed cable in a rural setting - eeeek, no thanks. Putting it underground and in conduit, we're getting difficult now..
I'll stick with my damn solar setup..
Hey I love your enthusiasm, but I don't think we should encourage those less knowledgeable to start a wiring hobby.
Off Grid system are still subject to Electrical standards and limited to 100 DC/AC, the client could be liable should someone be injured / insurance may not payout in case of a fire.
The 1500 W unit does have dc range 80-420V DC - so they could build a 3 string array at a max of 100v and hope that the controller can operate at a higher current. However 3 string open circuit would exceed 100volts and would be lethal
You did all that for OP already? That's very kind of you.
I'm that kinda guy..
Much appreciated all the suggestions.

just sell the battery on gumtree…
