Sunforce 11134 200-Watt DC to AC Modified Sine Wave Inverter

I didn't have this exact one but a 200 watt sunforce like it. It worked great for a few years then gave up on me. i could never go near 200 watts with it . In fact 4 CFL light bulbs 23 watts each would cause the whole thing to shut down.

Background:

Bought a solar panel kit from Harbor Freight. Kit doesn't come with inverter. Bought an inverter (which looked more

like a car inverter) from Harbor Freight too. Charged up the battery to 12+ volts but the inverter would squeal and not

work. Read instructions that it would do this under 13 volts. Returned that inverter.

Experience:

Bought this Sunforce inverter. It works perfectly for the solar panel kit. It doesn't squeal until less than 11 volts

or so. And from reading the reviews here, it was stated that this Sunforce inverter fan would turn on even without a load.

Sunforce must have changed the design so that the fan would not start until there was a load because that is my experience.

I bought a coleman 55 watt solar charger panel. It came with a sunforce inverter that was dead out of the box. Called the number for service and all you get is a recording saying leave a message will get back to you within 24 hrs. After 3 days of this calling game I think they have no intention of calling back. Threw it in the trash and went to a local store and bought a different brand that works. Update-----Finally called and did take care of the problem.

I purchased the Sunforce 50048 kit. The inverter comes with the kit. I like that it has two plugs. The solar panels seem to work nicely. But, the inverter literally blew a fuse within 5 minutes. I hadnt even attached it to anything yet. Fortunately, I had a spare handy. It could just be a lemon. Either way, probably best to go with another brand.

Want Sunforce 11134 200-Watt DC to AC Modified Sine Wave Inverter Discount?

I bought this trying to find an inverter that would consume low standby power for a solor project that would run one hour per night. Certainly the people at SUNFORCE would have their stuff together and realize that a solor project must be thrifty since it has limited "income". If the inverter is powered up with no load, it should just sit there until it has work to do. The larger ones power up silent and have the fan come on when: A= The load increases generating heat, or B= the internal temp climbs making the fan necessary. This is just 2 more semiconductors guys!

This one, if it's powered up; the fan runs and runs. Doesn't matter if it's 35°F and there is no load on it at all.

Anyone that has PC's for years realize that fans last 5 years at best then it's on to the junkyard.

I have to find one with "low quiescent drain"...

Hints appreciated.
