. That is why I suggested the the relay controlled load be 50 to 75% of the pwm diversion load, so that whenever it turns on the pwm controller will be working, too.

[RE-wrenches] Sharp 62 Watt Shingle Installation Info needed

Wrenches, I just picked up 32 Sharp 62 watt roofing shingles that I want to install on my barn since it is time for a new roof. Has anyone had any experience putting these modules on a roof in conjunction with cement tiles, which sharp's data sheet says they integrate with. David Katz David

Re: [RE-wrenches] intermittent battery problem

was probably because of the 800 watt PV array and light loads. It would be interesting to do a real equalization and a capacity test to see what is left of the batteries.

Re: [RE-wrenches] intermittent battery problem

How old are the batteries? Did you do the hydrometer reading, or are you relying on info from the customer. It is easy toi misread a hydrometer. When was the last time the batteries were at 30+ volts? David Katz From: Ron Young [mailto:solarea...@solareagle.com] Sent: Saturday, October 08, 2011

Re: [RE-wrenches] intermittent battery problem

If it takes 2 hours of charging to get to 25.8, the batteries are very discharged. It should be that high as soon as you start charging with a decent charger. David Katz From: Ron Young [mailto:solarea...@solareagle.com] Sent: Saturday, October 08, 2011 11:01 AM To: RE-wrenches re-wrenches

Brian, I have that setup in the old AEE trailer. We used it for charging a plug in hybrid for a race. When ever the car was not plugged in, power went backwards through the SW4024 and charged batteries. The waveform worked fine with and SMA 1800, which has a 120 VAC output. David David
