Re: [RE-wrenches] Tech Support Issues with Sensata

Just so you know, AEE Solar still has a bunch of Magnum panels and controls, no inverters, no support though. At least until they find someone to take it all. Keep an eye out for other close out stuff too. But, yes they are still going and working on getting better. Brad Bassett Retired--- 1985

Re: [RE-wrenches] Hawaiian Tie in

I have no experience with the Hawaii connection, but another choice for a tap connector is the Ilso GTA type with cover. You don't have to cut the tapped line and don't rely on piercing it. Brad Bassett Application Engineer (ret.) 1985 Solar Eng Svcs -> Applied Power -> Applied Power (Idaho

Re: [RE-wrenches] Parallel Homegrid Stack'd Busbar

Note that MidNite now also makes 2000A and 500A versions of their BCB. With two Sol-Ark 15k you do need to use the 1000A version with 275A each inverter. I can also confirm that you do need to use both of the battery terminals in the Sol-Ark 15k for full power, or the Homegrid bus bars that Jason

AEE might still have some of those if I remember Brad. Retired On Thu, Jun 15, 2023, 7:41 AM Chris Daum via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Hi folks: > > > > Any chance one of you has this auto gen start module they can part with? I > do NOT need the one with the

Re: [RE-wrenches] Outback Board Repair

Regarding AEE and off grid support, I'm not really in touch with them much any more so I can't say. You could ask Glenn Hall, he'd be able to say if he's heard anything about hiring a new tech. Of course finding someone with much off grid experience would be hard. Glenn and Alex do have some

Re: [RE-wrenches] Tigo RSS Off Grid

I powered a MidNite LSOB transmitter from a Classic AUX, though the receivers didn't work with the Classic. The Classic is limited to 200ma output and the Tigo and APS transmitters are rated at up to 800ma input, so it might overload the Classic AUX output if they really do draw that much. I

Re: [RE-wrenches] Deka Duration

Read the warranty. Very limited uses to maintain coverage. Mfg by an Italian Co that is somewhat condescending toward customers. But of course East Penn is good to work with. My understanding is that they do work with the three phase Sol-Ark inverters. Brad On Wed, Feb 7, 2024 at 4:52 AM William

Re: [RE-wrenches] Schneider Rapid shutdown with 2023 compliance

Note that the MPPT disco RS works only with Schneider charge controllers. With any other charge controllers you'll need to use Fire Raptors. Specifically the power line type rsd do not work with classic cc. I see no reason why the Schneider units would not meet 2020 or 2023 codes. On Mon, Jan 1,

Re: [RE-wrenches] Non-battery string inverter options?

Growatt MIN. They're capable of battery connection but work fine as a string inverter at a decent price. Brad On Fri, Feb 23, 2024 at 4:09 AM Glenn Burt via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Fronius. > Solis > > -Glenn > Sent from my 'smart'phone, so please excuse typos

Re: [RE-wrenches] 120 Vac and 12Vdc mixed distribution system

I had a lot of trouble keeping QO breakers functional on a 12VDC distribution system. I'd have to move them around every week or so to keep a good contact on the plug in contacts. They seem to work fine on a 24VDC system. I went to using MNPV or MNDC breakers instead in PV combiner or other
