Our PSI2000N Series pure sine wave inverter

• Continuous output power: 2000 Watts
• Surge power capability (peak power):4000Watts
• Pure sine power!

Some guys live where cold winters are expected and three-day power outages too common. Many residents have gasoline, propane, or diesel standby generators. They don't. Their radiant heating system relies on electricity for an oil furnace and water circulation, and it is nice to have refrigerator, TV and computers working. Some items may be sensitive to non-sine wave power.
Our PSI2000N Series pure sine wave inverter has a 220 volt "traction" battery as well as a 12-volt auxiliary battery that is kept charged by a DC-DC converter. The traction battery is kept charged by the internal combustion engine (ICE) optimized for such use. At rest (assuming the power switch is on) the computer monitors the state of charge (SOC) and other parameters, running the ICE to keep the traction battery charged to a satisfactory level (40 - 80%).

At present the inverter is in the Prius' cargo area hard-wired to the auxiliary battery terminals. There is a 120 amp fusible link in the Prius' circuit to the DC-DC converter, so it is advisable to limit current to the inverter to less than that. There is a 100-amp fusible link in the positive cable to the inverter but I plan to substitute a DC breaker and polarized plug-socket disconnect. In operation the car and inverter are turned on, and a heavy extension cord connected to the home heating system circuit though a switch that disconnects grid power to just that system (otherwise hardwired to the grid). Other appliances are connected via extension cords. In addition to making sure that total connected label wattage is below 1,000, AC amperage draw is sometimes monitored with an inline meter (keep below 8.5). The Prius is in our garage with an exhaust hose to the outside away from windows and doors (and we have a CO2 monitor in our living area). The ICE goes on to maintain SOC and at least one internal temperature, and we stay warm, entertained, and on-line! To prove it could be done, we have used the inverter to power an electric weed whacker along our private road! This set-up won't run anything requiring 220v (water well, electric range, dishwasher, etc.) nor typical laser printers, microwave ovens, etc.
