[RE-wrenches] mod waveform LED dimmer

HI All, I’m asking the group for a very obscure piece of information. I have someone with an very old Trace 2012 mod wave form inverter and wants to use their new LED bulbs with a dimmer Does anyone know of any LED/dimmer combos that will work? thanks in advance jay peltz power

Re: [RE-wrenches] DC-DC converter for SQFlex

push and push and push and draw max amount of watts. Under normal load, it won’t of course. PV direct you’ll be watt limited, but with a battery, no limits up to max pump watt draw and you don’t want the converter to fail. jay peltz power > On Aug 21, 2018, at 11:17 AM, Gary Hig

Re: [RE-wrenches] SOC and LFP batteries and TriMetric

A follow up question to all of this: Does anyone know what parameters a BMS is using to determine SOC for lithium? A project I installed uses the Orion BMS jr for lithium batteries. It uses a normal shunt, voltage and also measures internal cell resistance to determine SOC. Jay Peltz Power

[RE-wrenches] Non breakable RV modules

Hi All What are good options for a portable module for RV use. One that you can move around, (it’s going to fall over)and connect with a cable to an camper. The old unisolar ones were perfect. Any recommendations are appreciated Size? 50-100 watts, 12v nominal. Thx Jay

Re: [RE-wrenches] SOC, FNDC, and LFP batteries

. I’ve got 4 meters that I compare and if they are full daily it’s about 1-2% difference between them. If it’s been 7-10 days since full, then they could be off by 10-15%+ off. Curious what others are seeing Jay Peltz power. > On Aug 18, 2018, at 9:40 AM, Jerry Shafer wrote: >

Re: [RE-wrenches] Cell Cracks

I had a module engineer tell me these are often a static discharge issue which happens during the lamination process. It’s not effecting the cell surface but the encapsulate above it. It’s not cracking but it looks like it. Jay Peltz power. > On Aug 14, 2018, at 7:31 AM, Dave Tede

curious others take on that. This potential project ticks all the boxes for rail-less install. Low heat, no critters, no leaves, low pitch, few modules, micro inverter, standing metal seam. Thanks in advance Jay Peltz power. ___ List sponsored by
