Can anyone tell me if this chinese inverter is a good buy.
MicroSolar 24V 3000W (Peak 6000W) Pure Sine Wave Inverter [INV-3000PS
I sent a seller some questions regarding it and i haven't got back a reply so i am posting the questions hoping to get some response.
The unit is rated up to 30v input.
I saw on amazon where a seller said this unit cuts out when the solar panel voltage regulator goes through its equalization mode (higher voltage) during cold ambient temperatures because it inaccurately calibrated on the high voltage side by the manufacturer. So I want to know if is when it reaches 30v it cuts off or when it goes over that voltage? Or is it that because it is inaccurately calibrated the 30v max input with +/- maybe actually 29v or even less?
The next question is that a seller complained that whenever it goes into the low battery alarm stage and even thou the battery voltage might rise up back to the required level there is no output unless you turn it off and turn it on again.
Is this issue cause from the fact that it is a momentary push button start inverter?

The way a "typical" inverter manually resets from low battery voltage is you have to turn off the main breaker/DC input switch to the AC inverter.
Do you need that large of AC inverter? 3,000 Watts on a 24 volt battery bank requires some pretty heavy (and short cable) wiring. For a "full load":- 3,000 Watts * 1/0.85 AC inverter eff * 1/21.0 volts battery cutoff = 168 Amps max continuous

Sounds like typically cheap Chinese made junk.
I have a 12v samlex and it works great.Solar hybrid gasoline generator, 7kw gas, 180 watts of solar, Morningstar 15 amp MPPT, group 31 AGM, 900 watt kisae inverter.

Hi,
I have no idea if this is good or bad stuff, but the comment like go for a Cotek, well... I had a 48v which cut at 60v, and now a 12v which cuts at 15v. So i guess a 24v will cut at 30v...
As for the warranty... -
You have to look at the specs closely. Samlex has two different product lines. One has higher DC input working voltage vs the other.
