[RE-wrenches] Big Ag water

You will not find a specific "solar pump" in that range, but that's normal. Pick the best standard 3PH pump that you can, through local channels - NOT with variable frequency drive. The solar controller will be your VFD. Nowadays, any pump motor is almost sure to be "inverter rated" for use

Re: [RE-wrenches] Big Ag water

Just did one. You have to do the math for costing the grid, a genset, and solar direct. The genset usually wins if the grid is not an option. You can easily find/replace pumps that are not solar direct. If you do the solar, you still need a genset and the electronics to support it. It is

Re: [RE-wrenches] in need of a Bergey XL.1 controller, 24vdc

I have a customer who replaced the XL controller with a Midnite Solar controller, using the dump load function. SO IMO you don't need to find the original necessarily. Not up on Midnite controllers, so can't give you specifics now, but can find out the details. On Wed, Nov 8, 2023 at 4:47 PM

[RE-wrenches] Big Ag water

Ag water wrenches,             I've been asked about the feasibility of pumping 2,000 gallons/minute (mid-day) from a pond to open discharge at 40 feet of head, 1,000 ft run.  PV direct. Multiple Grundfos pumps? Any experience appreciated Bill Feather River Solar Electric 4291 Nelson St.

Re: [RE-wrenches] Cable sizing for high current modules? NEC interpretation/guidance?

Choosing a higher insulation rating for the wire will increase current capability, if that works in your case. Larry Crutcher Starlight Solar Power Systems On Nov 8, 2023, at 10:06 AM, George McClellan via RE-wrenches wrote: Team; With the move to larger cells, some modules have an Isc

George: Appliance manufacturers have their own requirements that are not the same as the NEC requirements. As long as you are not modifying the manufactured assembly you are not responsible for compliance of that appliance. By appliance, I mean the solar module, microinverter, etc. William

Re: [RE-wrenches] Cable sizing for high current modules? NEC interpretation/guidance?

Hi George, It's good to see you're still with REC. I'd assume this would fall under the purview of UL rather than NEC. Anything that meets UL will pass NEC. With temperature derates I think you'd have had to go to larger wire long ago to meet NEC standards. It might be good to go to a larger

[RE-wrenches] Cable sizing for high current modules? NEC interpretation/guidance?

Team; With the move to larger cells, some modules have an Isc that is pushing the limits of 12 AWG wire. If I apply the rule of 156% (or 125% solar derate*125% continuous load derate) to an 18 Amp Isc module this will exceed the 25A that a 12 AWG wire can carry. I understand that the
