I am working on the design of my solar roof-mount as well. I am considering just using the inexpensive growatt grid-tie inverter so I can take advantage of net metering. All-in-one is great, but that 18kpv unit is about 4x the cost, so that is why I'm considering a cheaper way of getting solar...

That is a good point. However, considering how cheap it looks like this route will be, I am leaning towards risking a surplus at the end of the year. The only thing I can't get away from is their $35 monthly service fee. But I suppose it's fair given the net metering agreement.

Since my roof space is limited, and I don't have alternative mounting surfaces, I believe I will need to maximize roof utilization if I hope to achieve 100% offset. Signature solar has a nice flat-rate freight shipping price for $5k+ orders, so I may be able to easily add some smaller...

That is a good point about the panels. That and they are 18.5% efficient and the next step up is 20.5% canadian solar 400w panels for $.407/w. My roof layout is triangular so I might try and fit the larger panels. But if they are too bulky, it may turn out I can get more solar on my roof with...

I had a consultation with Sunrun the other day and they quoted $54k for a 11.2kw grid-tie system. That is just insane, and I figured it would be, but still wanted to see what they were offering. The ROI on that is a TOUGH sell. We are fortunate enough to get 1:1 net metering from our utility...

What is a "free nights plan"? Are we talking cell phone minutes or electrical service?

I agree that it would be overkill for golf cart needs. My thought is that if I can fit a large enough battery pack in the golf cart, then it can serve as a substitute for a dedicated solar battery pack.

How did you run the cables for the battery pack? Quick-connect, or more permanent when needed?

I suppose I can dissect my post into two portions: 1. Most interested if anybody who has a golf cart for casual transportation around their community, and also has a solar/inverter/battery setup, has used their golf cart's fairly large battery pack as a "mobile/removeable" energy storage source...

Hmm.. I am not familiar with those nuances. It sounds like more research is in order. It has a 3-phase AC motor rated at 5kw, so I figured a 150-200A bms wouldn't break a sweat

I have a golf cart with a pretty large battery compartment. It currently has 6x 8v lead acid. An idea I am pondering is replacing the exiting batteries with a DIY 320AH 48v Lifepo4 battery pack, and making it accessible as the battery source for a home backup inverter (similar to the F150...

I haven't picked any up, but have recently reconsidered. However it seems that shipping has gone down. They quoted me about $195 freight for 10 panels

The battery's recommended Bulk voltage is 57v, float 56.5, and absorb 56.5v

I'm having issues with my system not charging up the batteries all the way. I suspect it has something to do with the inverter/charger, however their support I believe is in china and I have had very delayed communication with them so I wanted to run it by you guys to see if you have ideas...

Hi Jay, I researched something similar a while back. The most cost-effective solutions seems to be made by Deep Sea Electronics. It is programmable so you can calibrate it to work with your inverter output: https://www.deepseaelectronics.com/genset/manual-auto-start-control-modules/dse3110
