Re: [RE-wrenches] Has anyone had Magnum Energy PT-100 controller failures

Perhaps I should rephrase my question: Has anyone else been selling the PT-100? If so, how many? Any failures? Early on a tech told me that I’m the only one experiencing the failures. Larry On Jul 28, 2016, at 4:27 PM, Starlight Solar Power Systems <la...@starlightsolar.com> wrote:

Hello Battery Wrenches, I have installed about 35 of the Magnum PT-100 charge controllers since November 2015. I have had about 10 fail, another one just today. The problem we have is the same every time: network communications fail which causes other problems until you remove the network

Re: [RE-wrenches] Replacing grounded inverters

Be nice William ;-) Hi Gary, DC can not be transformed without converting it to AC first then back to DC again. Probably not feasible to do while tracking the MMP. Larry Crutcher Starlight Solar Power Systems On Jul 22, 2016, at 12:50 PM, William Miller <will...@millersolar.com>

them with remanufactured units. Bill, the typical failure is Voc of about 10 volts. However, the failure can be intermittent. For this reason, any modules in the date period should be replaced even though they appear to test OK. Larry Crutcher Starlight Solar Power Systems On Jul 2, 2016

Re: [RE-wrenches] Winter Battery Maintenance

for long term non-use. You can simply discharge the battery to 50% then turn off the battery and walk away. When you return in 6-7 months, you will find it at the same SoC as when you left. For long term seasonal storage, that is all I recommend anymore. Larry Crutcher Starlight Solar Power Systems

Re: [RE-wrenches] Winter Battery Maintenance

I agree with Todd and Bob, leave the PV solar on, EQ off. I also instruct my customers to reduce the absorb timer to 0.1 hours. Since the battery is staying full, there is no need to spend time above cell gassing point which will increase water loss. Larry On Apr 30, 2016, at 10:28 AM, RE

Re: [RE-wrenches] Inverter/AC pump compatibility question

You can tell the grey-beards from younger wrenches…..A square wave is generated and modified to act like a sine wave, thus, it is a modified square wave. As I see it, in order to deceive the consumer, the term "modified sine wave" was created. Larry On Apr 26, 2016, at 5:57 AM, Carl Hansen
