Review of the Duracell HD600 Powerpack

Experiments / ProjectsAfter a firm 48 hour charge as per the directions for first use, I hooked up my new Duracell HD600 Powerpack to my IC706MKII and gave it a test run. I spent the early afternoon sending CQ on 20 meters ssb voice using 100 watts threw my Buddypole. Band conditions were terrible which was good for the longevity test of the powerpack ( more transmitting and less receiving). Bottom line, I was worried about wearing the powerpack out with my long winded CQ's. Instead,...

Solar & Battery back up for the home

Experiments / ProjectsGOALS:
1. To be able to run my heating system and some lights for a minimum of 5 days or longer during a prolonged power outage.
2. The above assumes that Keyspan is still providing natural gas. As a backup, a generator is supplied that will be tri fuel (natural gas, propane & regular gas). The generator will provide topping off of batteries so nighttime operation will remain quite. If Keyspan is providing gas then during the day the generator can provide additional power. If Keyspan is not providing gas, then the generator will be powered by two large propane tanks and the house will be heated with high efficiency (so they say) electric heaters.
3. To “be green” and save some money (after the 6-7 year calculated pay back). With the price of oil going up as fast as it is- it might be sooner rather than later.
