1. UNLESS your Inverter draws less than 100 amps DC current in Invert operation, you NEVER install a battery disconnect on the Feed Positive cable to the Inverter
2. You can install a 200 amp rated Disconnect switch if you have the smaller 1000 to 1500 Watt Magnum Inverters.
3. A quick way to disconnect the remote is either go to the Inverter and disconnect the Phone Type remote cable, takes 5 seconds. OR pull the remote panel and disconnect the same cable. Takes 3 or 4 minutes.
4. Disconnect the Negative cable at your House Batteries when storing. This is the BEST solution as most OEM's also route the LP/CO detector direct to the batteries and are not turned OFF when the battery disconnect is used. Doug
