How much energy can we make per gallon of diesel fuel? I'll be testing an Army generator's fuel economy while re-charging my off grid solar battery bank. The military generator is model MEP-831A. It's a single cylinder, Yanmar L-70 diesel engine. In the winter, there isn't enough solar energy to keep my battery bank full. I supplement my off grid system with a generator. I'm curious which generator is the most efficient. In past videos I've tested my Honda EU6500 gasoline generator, and I've tested my home-built Harbor Freight generator using a car alternator. Below are the video links to those videos: Honda Generator Fuel test: https://www.youtube.com/watch?v=kQTFPMDE_F4 Home-built Alternator-generator: https://www.youtube.com/watch?v=yQTCVyxdauo --------------------------------------------------------------------------------- Signature Solar Affiliate Links: Chargeverter, 100A charger: https://signaturesolar.com/eg4-chargeverter-gc-48v-100a-battery-charger-5120w-output-240-120v-input-pre-order/?ref=4_rHcgZ9x-TiF- EG4 Battery Bank: https://signaturesolar.com/eg4-lifepower4-lithium-batteries-kit-30-72kwh-6-server-rack-batteries-pre-assembled-enclosed-rack-with-door-wheels-busbar-covers/?ref=4_rHcgZ9x-TiF- Schneider Inverter: https://signaturesolar.com/schneider-conext-xw-pro-6-8kw-inverter-charger-48v-120-240v/?ref=4_rHcgZ9x-TiF- ---------------------------------------------------------------------------------- Disclaimer: My videos are in no way intended to be instructional "how-to" lessons.
