Auto Transfer Switch installed, Geodesic Quonset lumber arriving.
The first load of lumber for the Geodesic Quonset was delivered. Construction starts immediately.
The Automatic Transfer Switch for the VeggieGen was installed today. It worked flawlessly. With the generator off, the battery bank powers the house through the Cobra HighGear 2kw MSW Inverter. Since this Transfer Switch is set up for 220vac, the two hot positions for the inverter (shorepower) are jumpered to supply 120vac to both sides of the AC Panel. Do not do this if you have a 220vac breaker feeding a 220vac appliance. The VeggieGen (3 phases of 120 vac per phase) has two 120vac legs feeding the generator positions on the transfer switch. The output of the switch feeds the main breaker of the AC Panel. The wire is 10/3 with ground which handles the 30 amps per leg we can pull from the gen. 30 seconds after the Generator is started, power flow to AC panel is smoothly switched from Inverter to Generator. The Computer and Satellite Receiver don't even see the change. You can also get more info on our PV/Wind System at our Wiki Site.
