Re: [RE-wrenches] Tigo inverter experience

I do not have a lot of experience with Tigo equipment, almost all using their optimizers with CCAs and TAPs. The 2 things I can say is after getting my head wrapped around the setup and commissioning process (which is not the most intuitive process), I haven't had much trouble with them (again onl

Re: [RE-wrenches] Tigo inverter experience

Hi Dave I haven't tried their micro inverter or ESS, but so far all the products that I've used from Tigo including the RSD switches that melted have been problematic. Personally, I wouldn't use their products. Vince McClellan President NABCEP PV Professional p: 541-485-8122 a: 860 Conger St.

Re: [RE-wrenches] Tigo RSS Off Grid

Sorry Howie, I now see you were specifically asking about inverter/charge controller combo solutions. I should have caught that detail. Still seems as an easy workaround though if for some reason the inverter manufacturer failed to isolate the 12v output independent of the AC output LBCO. Perhap

Re: [RE-wrenches] Tigo RSS Off Grid

The 48v to 12v DC converter approach should be immune from the inverters LBCO since it lives on the battery side of the inverter/bus. I’ve done a few systems using Tigo’s without issue. The main concern is you now have a DC load attached to the battery output lacking DC load protection that coul

Re: [RE-wrenches] Tigo RSS Off Grid

With the Sol-Ark (or other DC coupled inverter/charge controller combinations such as the Envy), will the system pass through solar power if the inverter has turned off on LBCO? If not, then these alternative methods for powering the RSD signal generators won't make a difference, correct? And does

Re: [RE-wrenches] Tigo RSS Off Grid

Hi Jeremy... The Classic AUX outputs will put out about 13 volts and allow up to about 200 mA maximum. That might be enough to power the transmitter. That is only about 2.5 watts so might not work directly. 🌜boB🌛 Docked at Trinidad/Tobago today.  Great sun here.  Have only seen one PV modu

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 teste

Re: [RE-wrenches] TIGO/ Classic 250 fights?

In addition, an SPD is supposed to keep any input lines to the equipment from breaking over the insulation. For the Classic, the hipot voltage is over 2000 volts to chassis (gnd). If the SPDs are grounded and connected well they should be able to do their job unless maybe it is a direct s

Re: [RE-wrenches] TIGO/ Classic 250 fights?

The SPD will (or, should), "clamp" the input voltages, both positive and negative to ground at the MOV voltage rating during a lightning strike. The SPD 300 starts at about 500 volts on each leg of the SPD. The 600 SPD is higher voltage of course. Since, on the PV input side, the MOVs appea

Re: [RE-wrenches] Tigo and SMA AFCI - Was: AC coupled, grid-tied Sunny Island - contactor & bypass

From Robin It has been pointed out that the Tigo modules can and do blow up some charge controllers and inverters. When a charge controller or inverter has fairly fast tracking, the two units fight each other. We have found Classics using the fast tracking mode will blow up with Tigo's in the

Re: [RE-wrenches] Tigo to go?

Marco, The only argument you can make for a system like yours is to say that if the modules degrade at different rates, then the Tigo optimizers make sense. Otherwise, I can't see how it could be anything but a slight loss. Tough call for $15k. Other attributes like monitoring and shutting off
