Spartan Inverter??

dtcerrato · April 28, 2020, 07:28:08 AM

Wondering if anyone has experience with the SP3322 or Spartan Inverters in general.
It weighs in at 57 lbs & is a low frequency unit. Never heard of them & the price is almost worth experimenting with... Rated @ 3300 watts @ 12 volts and will take a surge of 9900 watts for 20 seconds. Advertised for just under $900. Comments?

Spartan Power located in Reno NV is battery cable manufacture,they buy the inverters from Chinese co I don't if they are good are not, the price is cheap for a good inverter 1/2 of a Magnum made in the US

",they buy the inverters from Chinese"

10-4 on the responses. It's the half price and the good reviews - only the both together that took my attention... Still weighing it out... Thanks

Dan, come on. Chinese propaganda - they pay 5 cents for every ++ review.

The couple negative reviews on the charger section probably is tipping me away from it. Like you said - the charging circuit is probably more critical than the inverter circuit...

A few thoughts on it:

1) 3300W at 12V is 275 amps! Allow for voltage droop under load unless you have a huge battery bank, and you could be seeing a 300 amp draw, albeit briefly. Even 4/0 cable is barely enough.

2) The Amazon ad extolls its "Ultra low 18W Power Save Mode helps saves battery life". An 18W continuous draw on the batteries can run them down surprisingly quickly. I would want to see no more than 10W consumption in Sleep mode.

3) Weight is an indicator of quality, so at almost 50lbs it should be solidly built, one hopes.

4) It look like a Magnum, slightly. Sometimes one can buy factory-reconditioned Magnums for a lot less than normal, complete with warranty, and with all the usual Magnum field-serviceability and quality. I bought my reman MS2000 for just under $1000, and I'm happy with it.

5) A 50 amp charger is not much. Is it Power Factor Corrected, or does it have a lousy PF that will tax your generator?

Questions, questions.
