Go Power! TS-30 30 Amp Automatic Transfer Switch

The Go Power! Transfer Switch 30 amp (TS-30) provides automatic power switching between two separate 120 volt AC input sources. Some inverter installations integrate the inverter directly into the AC electrical system. An automatic transfer switch is usually installed to allow both your inverter and shore power to alternatively feed the circuits and prevent AC back feed. The Go Power! TS-30 is a 30 amp AC switch that automatically connects shore power (when available) to your breaker panel. When unplugged from power, it then connects your inverter output to power your circuits.

  • Voltage: 120 VAC
  • Amps: 30 Amps
  • Dimensions: 9.65”L x 7.28”W x 4.75”H
  • Weight: 3 lbs.

Great Auto-Transfer Switch with instant failover, and instant failback (if configured to do so).

Great Auto-Transfer Switch with instant failover, and instant failback (if configured to do so).
I replaced a manual transfer switch that I had in my shed that had Shore and Solar power connected. As the batteries ran out of power and the voltage dropped too low, the inverter would trip / the inverter alarm would go off and it would cut power from the shed. Not a huge deal as there's nothing essential in there, it was more my experimenting with solar, for lighting, the shed fan, and recharging of the mower battery. I just got tired of running outside switching back and forth from shore the solar setup that powers the two sealed 'car batteries'.This a automatic transfer switch did the job perfectly. I remember seeing these a few years ago when I first toyed with building a 'solar shed', but I don't remember why I didn't go with this over the EZ Generator Switch (https://www.amazon.com/gp/product/B00FADDE0A) - especially since this one is cheaper. Probably just because I didn't need to hard wire it and I could plug a cord directly into it from the inverter.One thing that I remember not liking was the 15 second delay in returning to the Primary power supply, but after re-reading / researching this topic, they've addressed that issue with the addition of some jumper pins coming off of the little circuit board that's at the bottom of the unit. I just found an old 'jumper cap' from an old computer (like this here: https://www.amazon.com/ZYAMY-2-54mm-Standard-Circuit-Connection/dp/B077957RN7) to bridge the pins and then tested. It would instantly failover to the secondary and instantly failback to the primary after that. Easy day. The updated instructions from their web site (https://s3-us-west-2.amazonaws.com/catsy.549/MOBI_MAN_GP-TS-30.pdf) show how to do it (see page 5).My setup is as follows:Solar Panels --> Charge Controller --> 2 Batteries --> 1000w Inverter --> Primary / 'Dominant' Supply on the TS-30 Automatic Transfer Switch.House Power --> Secondary / 'Default' Supply on the TS-30 Automatic Transfer SwitchFrom there the Load goes to a Two Circuit Panel ( https://www.amazon.com/gp/product/B00002N7MM ), that has a 15 amp circuit breaker that goes to the load.So far so good - now I just need to figure out why the GFI that's in the basement between the main panel and the garage trips during transfer. The shed gets it's 'shore power' from an exterior outlet that's connected to the garage and that GFI is part of the circuit.UPDATE:At first I thought it was due to load, but then realized that it would trip the GFI in the basement when changing from 'shore power' back to Solar... In both Solar and Shore mode, the outlets in the shed work fine. In further testing, it looks like the basement GFI only trips when going back to Solar, but ONLY if switching back and the inverter alarm was previously going off for something like a low voltage alarm while powering chargers overnight. When the sun comes back up and the batteries are back to 12+ volts, the alarm still stays on. Have an e-mail in to Renogy about this to try to get it all sorted out.
