I'm considering getting an inverter so I can run some low power fans in my greenhouse from a 12V battery. The battery would be charged from a solar panel, and I'd have some kind of thermostat. I'd also consider this for emergency use, say keeping my fridge/freezer running. How about a microwave? I have telecommunications on a dedicated DC UPS.
You can get pure sine wave, modified sine wave, and unspecified. Examples:
- Modified sine wave $170 for 300W
- Unspecified $70 for 500W
- Pure sine wave $380 for 350W.
Can fans, a fridge, microwave, run off all or any of those? Obviously pure sine wave is best, but I'm looking for "good enough".
Update - I'd like to refocus the question. Could a cheap inverter like the "unspecified" one above power a couple of desk fans? They're typically low current.
