Hmmm…it’s Generator Day here at Zeropolis. Drag the EU2000 out of its protective Hardigg case, set it up, run some high-draw appliance off it for a while to make sure eveything gets a workout, clean it up, and then back to storage for another month or two until the next Generator Day. The more I think about it, the more I think that this is going to be the year I finally get the stupid battery power supply done. It’s a remarkably simple plan brought to ruin by my unparalleled laziness. See, when the power goes out I have, really, only four power needs:
- Communications – running scanners, radios, internet, computer, etc.
- Security – surveillance and associated systems
- Lighting – It’d be nice to be able to not walk into the furniture
Now, except for the fridge/freezer issue, which is where the generator comes in, all the rest of that stuff can quite happily run on a DC battery supply.
The laptop runs on DC, as does the radios, scanners, and router. Same for the surveillance system. And the emergency LED lighting runs on DC as well. And since there is no need to have an inverter to turn the DC into AC, there isn’t the usual loss of energy accompanies such things. In short, if everything runs on DC I get more bang for my electrical buck than if I tried to run it on AC.
Ideally, what I’d like to set up is something where the batteries charge as needed off the house current, and when that fails they charge (albeit at a slower rate) off a couple of strategically placed solar panels. I then run the wires into a room where I plan on keeping all the critical systems. It doesn’t have to be a huge system…it just has to be big enough to run some fairly low-draw DC stuff for three or four days without a recharge.
Last time we had an outage here it lasted quite a while. I rather liked having cable TV and internet while the rest of the neighborhood was dark.
