Re: [RE-wrenches] intermittent battery problem

Client gave me the float readings from the MX and they look ok but there's been no float in the last couple of weeks. I've been thinking an electrical contact problem either inside the E-panel, the inverter or the battery causing the unexplained voltage drop. Brian and Mark you may be spot on. I

Re: [RE-wrenches] intermittent battery problem

I once saw a brand new L16 battery that would read the proper voltage (6.3 VDC) and had good hydrometer readings, but the voltage would drop to zero when a load was applied. We were even able to do a dead short with a piece of #10 wire with only a faint spark visible upon connection, and then no

I would load test each battery individually using a common "toaster heating element" tester.I'm betting on a bum battery in the string. Original Message Subject: Re: [RE-wrenches] intermittent battery problem From: Ron Young Date: Tue, October 11, 201

Re: [RE-wrenches] intermittent battery problem

Ron, Sounds like you might have a voltage drop in the system at point of measurement. A large voltage drop can happen for a few valid reasons. 1. High current demand. > Trimetric or better yet PentaMetric can show this demand. 2. Poor Cable connection. Visual / Thermal inspection or local Vdc

[RE-wrenches] Re-shingling roof

Hey Wrenches, I know it has been discussed on this list, but i'm not having any luck finding any threads on how to deal with re-shingling an asphalt shingle roof with a PV array already on it. I have a potential client who is asking (somewhat concerned) about this scenario and i'm loo

Re: [RE-wrenches] intermittent battery problem

Wrenches, I received some additional info from the customer this morning. They have asked me to hold off my visit until they get a few more clues but some of what they are telling me doesn't necessarily jive with a sulphated battery. Would appreciate comments - here's a quote from their email:

[RE-wrenches] Renusol CS60 flat roof racking.

Wrenches, Does anybody out there have experience with the new Renusol CS60 flat roof racking system. We are about to install some, and I was hoping to get some feedback on how it went. It seems like its going to be challenging to get these things to look good. Mucho Gracias in advance! Sunny Reg
