Re: [RE-wrenches] AC Coupled with Generator

Ray, I’m curious about what you mean by not doing a 3 stage charge. While PV charging in coupled mode (off grid), the battery will reach your absorption set point. Is this triggering the GT inverters to shut off or does the battery inverter absorb timer run at all? I would think the absorb time

Re: [RE-wrenches] Control board Kohler 14 RES

Magnum Energy inverters have no capability to send current to the grid (generator) through their inputs. Sounds like BS to me. What is this mystery board that blocks AC current one way? Larry On Aug 25, 2015, at 11:18 PM, Mac Lewis wrote: Hello wrenches, I've got an issue I'd like to put ou

Peter, Fronius has some of the most ignorant people working for them. It took me over a year to receive payment for an inverter swap that they diagnosed as having failed. After I returned the old inverter they claimed nothing was wrong. Run from Fronius! Thank you, Larry On Sep 3, 2015, a

William and Wrenches, I have pondered situations like this one and wonder the following: If a high voltage DC solenoid were placed at the PV array and the coil was controlled by an arc fault detector along with a means of manually disconnecting, would that not work to satisfy shut down require

Hello Howie, I attached it to my email on 9-24-2015. In brief, a HV relay disconnects the PV array and optional relay disconnects the battery. Midnite plans to add the arc fault Aux feature. Here it is again: I asked Midnite about using the Aux circuit for control for ground or arc faults. Th

Re: [RE-wrenches] Five L16s in a 24V string?

Since multiple batteries failed ("the one that always fails"), did he buy one new battery each time and tie it to the old failing one? Or, did he start with a new bank and create the parallel at that time? Since he’s an “old timer” he may be mixing different age batteries in the bank. I see this
