Re: [RE-wrenches] Golf Cart as temporary off-grid PV

For disconnects, I'd just use Andersen quick connects.  That's what they use on forklifts and other industrial battery operated machines.  Also, the Magnum would act as the vehicle charger, and would be a much better charger than the stock golf cart models. Ray Walters Remote Solar 303 505-876

Re: [RE-wrenches] Water Pumping 24/7

Hilton: A valid point. However in this region wells often do not recharge as well as we might like. In these cases, to meet gallons per day you have to pump long and slow--more hours per day than the sun will be up. That means of course generator or battery storage. The economics have shifted

Forgot to add: I’m talking about the belt drive piston pumps out there so you can install a low voltage DC motor if you want. Hilton Dier III Renewable Energy Design Missisquoi River Hydro LLC ___ List sponsored by Redwood Alliance Pay optional member

[RE-wrenches] Water Pumping 24/7

Here’s a lateral take on this. A 500 gallon poly water tank is far cheaper than the batteries needed to fill it. Years ago I rigged up a seasonal pump system for a man who had two ponds on his property. The lower one was well fed by a spring but the upper one wasn’t. I used a 200 watt DC pisto

Re: [RE-wrenches] Golf Cart as temporary off-grid PV

That's what I was thinking- a MS4448 would be a nice option with a good surge rating. I'm trying to make this work with little to minimal equipment onboard the golf cart. Ideally, the battery would connect to a stationary inverter/charger at the house via a cable/connector. The PV would be permane

Re: [RE-wrenches] Golf Cart as temporary off-grid PV

Most carts run at 48vdc these days.  They either have eight 6 volt batteries, or six 8 v batteries.  I would think that would make a good match for power backup with a 4kw range inverter like the Magnum MS4448. Ray On 3/15/2022 12:18 PM, Nick A Lucchese wrote: Not sure what the golf cart flee

Re: [RE-wrenches] 24/7 Water pumping

The Midnite Classic can go higher to 72v stock, and they have models that can work with 120 vdc batteries. Ray On 3/15/2022 12:19 PM, larrycrutcher wrote: Hi William, A charge controller may not be needed if you are running the pump direct. By designing the PV array so that the Isc is higher

You'll have to relate those stories about Hart's Tansverter to us Nick. . He's been so vocal and self-promotional lately I actually toyed with the idea of purchasing one to put it to the test 😆. . On Tue, Mar 15, 2022, 11:18 AM Nick A Lucchese wrote: > Not sure what the golf cart fleets are the

HI All, Any thoughts about APsystems vs Enphase micro inverters. They have a new DS3 line that looks quite good. Thanks in advance Jay ___ List sponsored by Redwood Alliance Pay optional member dues here: http://re-wrenches.org List Address: RE-w

Re: [RE-wrenches] 24/7 Water pumping

Hi William, A charge controller may not be needed if you are running the pump direct. By designing the PV array so that the Isc is higher than the maximum load demands, and the Voc is less than the maximum operating voltage, you can run PV direct without a controller. Use a high voltage relay (

Re: [RE-wrenches] 24/7 Water pumping

Windy: Thanks for the info. I have been in contact with Sun Pumps. They can sell me a pump that will work off of a high voltage battery bank (greater than 90 VDC and likely much higher). However they cannot provide or recommend a charge controller to output PV charge at the higher voltage. Do you
