Off-Grid Power Systems and Surge Protection
Is my off-grid solar system and back-up generator connected right? Surge Protection for an Off-Grid System.
Circuit Balancing and Surge Protection
Electrical Question: Is my off-grid solar system and back-up generator connected right?
- I have an off-grid solar system with a back-up portable generator (Briggs and Straton 5000 watts.)
- I used the generator to power the house when the battery bank was low and there was no sun light. Everything worked fine.
- I ran the generator for 1 hr. About 3 weeks after this event, both my microwave and stove (Frigidaire Professional Series) went on the blink.
- It appears that something has “fried” the components. Are these two things related?
Additional Comments: Great!

Surge Protection for an Off-Grid System
Surge Protection for an Off-Grid System – electronic circuitry can be damaged if the voltage from the generator is not stable. This happened to us a few winters ago while on generator because the refrigerator and the septic pump turned on at the same time and created a power surge that burned up a surge protector that was installed for a computer.
Important Circuit Balancing and Surge Protection for an an Off-Grid Solar System
- Without a doubt, electronic circuitry can be damaged if the voltage from the generator is not stable. This happened to us a few winters ago while on generator because the refrigerator and the septic pump turned on at the same time and created a power surge that burned up a surge protector that was installed for a computer. The same may be true in your case, but what puzzles me is why it took 3 weeks – it just does not sound right. Does the system have a filtered or conditioned output which prevents dips and spikes? The quality of the power must be maintained to prevent damage from occurring.
- Another thought I have is if the stove is natural gas or propane requiring only 120 volt ignition and controls, and if the microwave is on the same circuit? If so then this circuit should be conditioned. Keep in mind that depending on the size of the microwave oven it may require a dedicated circuit. If your system produces 120/240 volt then load balancing would be advisable.

Renewable Energy Tips
- A new home provides the best opportunity for designing and orienting the home to take advantage of the sun’s rays.
- A well-oriented home admits low-angle winter sun to reduce heating bills and rejects overhead summer sun to reduce cooling bills. See the Heating and Cooling section for more about using passive solar energy in your home.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
