Build your own Emergency Power System

We will be running classes on assemblying a emergency power system and teaching the basics of off-grid power systems. Based on an inexpensive lawnmower engine and a car alternator, it includes storage batteries and an inverter. Solar PV and Wind charging will also be addressed. Check out the charge controller for this application.

Nov. 12th in Winthrop, NY, 10am

Additional classes will also be scheduled.
Classes are $75 and lunch will be provided.

Measuring Power Consumption


Living off-grid, either in an RV or a renewable energy powered home, there is a great need to be able to measure the power consumed by various devices. This is necessary in order to size your power generation devices, like PV Panels, your distribution devices, like inverters, and your storage batteries.

Even in an on-grid home, a Kill-A-Watt is good to help you conserve energy by comparing energy comnsumption of various appliances for purchasing decisions.

For 120vac devices, we use a Kill-A-Watt to monitor and predict daily power consumption. This unit monitors Volts, Amps, Watts, VA, HZ, PF, kWh, and hours used.

For DC devices, we use a “Watt’s Up” watt meter which replaces an ammeter, voltmeter, wattmeter, Amp-hour and Watt-hour meter:
