Re: [RE-wrenches] Low Frequency transformer off-grid inverter options

Hi Mac The radian is low voltage transformer Based. Has hella surge capacity I would consider what web based monitoring system he wants and go with that platform. Regardless of system I’d install soft start/vfd on the larger units. Just easier on everything. The solark 12 doesn’t seem to

Re: [RE-wrenches] Remote battery disconnects

Good point Glenn. My question is if this system is in its own building. If so it is probably easier to convince the AHJ about not needing a remote battery disco. JayOn Jan 27, 2023, at 12:46 PM, Glenn Burt via RE-wrenches wrote: Does the AHJ really want the batteries disconnected

Re: [RE-wrenches] Remote battery disconnects

HI William B, That is a good point. And even beyond the potential CC damage, since your now potentially powering the inverter it could actually stay alive ( I’ve seen this happen ) or it can cause a voltage spike from the CC which can damage the inverter which I”ve also seen. I don’t know

HI Brad, I was just about to hit send on those exact wattages, yes completely agree. As a sort of joke, the self discharge of the batteries is probably more than what she could make in a day. Jay > On Mar 16, 2023, at 4:29 PM, Bradley Bassett via RE-wrenches > wrote: > > I tried this

[RE-wrenches] absolyte GP battery question/ sideways mounting.

HI All, I was just contacted by someone who has a 6 yr old absolyte GP 100G33 battery that has lost a lot of capacity. The manual only lists a horizontal install, but this was installed on its side which I”m guessing was due to space issues. I am thinking that isn’t good for it, but
