| Stacking Inverters In a lot of cases you need 220 volts to run items like a clothing drier. It is better to switch any heat making devices that are powered by electricity away from inverters and solar to something a little cheaper like propane. This alone could save you greater then $10,000 in solar panels, smaller inverters and labor to install them. But if you do need a higher voltage you can get inverters that you can stack to up voltage or you can stack them to increase power output. No matter how you want to do the project there is inverter for the job. Some of the newer inverters like the Xantrex XW inverters are 240 volts and need no stacking but can be to add amps. |
| Inverter battery cables are no place to skimp in cost because of the high amperage inverters can pull. I like talking about the monster of the all house hold devices. The 1800 watt hair drier that so many women can not live without (that was said with a smile). A little math on this one, at 1800 watts, 120 volts (watts divided by volts = amps) gives you a full 15 amp pull (an inverter can handle this with no problem). But, If you have 14 awg wiring in your home you will make some wires a little warm. Oh Yeah, back to my point I started out to make about the inverter battery cables. If 1800 watts at 120 volts is 15 amps do the same math at 12 volts, if your battery bank is setup at that voltage. Did you get 150 amps? Do you know you can arc weld at less then 60 amps? You as well know something other then just the hair drier will be pulling power from your inverter. Maybe a 1200 watt coffee pot and a couple of lights. So the battery cables need to be rated for the peak amperage of your inverter plus 125%. The larger and shorter the cables from the inverter to batteries the better. Make sure there is a fuse and or breaker or both in the line. Most systems use a negative ground which means you never want to fuse the negative wire of the inverter or anything else. Doing so could give you a jolt when working on the system. When the negative wire is open and the positive is still connect you can get a shock. |
