New 6KW pure sine inverter/ 100amp charger: £180!

[DBA Forum (B) - David Beaumont]

I've just bought one of these, I didn't get it for quite as low as £180 but I see they are going for between £180 and £250 plus £35 delivery from Ireland. This seems remarkably cheap. Type 151427394400 into ebay. There are also 12V/24V 8KW, 5KW and 3KW ones, the auction sales are much cheaper than the fixed price (£439)

It arrived quickly but I have only tested its basic functions so far, not installed - it is very heavy and I haven't figured out how to secure. Claimed peak output is 24KW, I don't think I can test that high.

It will replace my previous 7 year old 1.5KW pure sine of the same Taiwanese brand, 'PowerJack'. The 1.5KW is fine as long as you take the rating with a pinch of salt - actually 1.2KW, hence the upgrade.

sounds good and cheap. Can you set the charging unit to different batteries types, i.e. traction or normal, so that the charging cycle can be set to the batterie?

Some of the language in the blurb looks a bit 'far eastern'. Examples:

'PLEASE NOTE: for battery charge mode: before charge the battery, please turn off the inverter first, connect the AC power cord with home AC source and inverter, then turn on the inverter to start the function. When finished, need to turn off inverter first, then disconnect the AC power cord. Otherwise the PCB board might be damage due to high voltage spark.'

'b. however, this inverter can decide how long you want to use, the more high capacity battery you connect, then you can use whatever you want'

It may be fine but is there a reason why it's so cheap?

Taiwan is indeed the far east. I don't think there are many bits of electronic kit nowadays that aren't far eastern in origin. Agreed the manual is written in Chinglish and often has to be read a couple of times. It is also somewhat sexist with an abundance of pics of bikini clad women.

The charger has a switch to change to 14.0V, 14.1v, 14.4V, 14.4V, 14.6V, 14.8V, 15.1V and '15.5V for 4 hours'. It claims to be 4 step charging constant current. I have tried it on a small 12V booster battery and it dropped from an initial 14V to 13.5V OK. However it did trip my 32amp mains overload a few times I am hoping this is because I used a tiny battery. My old inverter never had a charger function so this is a bonus to me.

As to the £439 fixed price this looks right to me, I assume the Victrons etc are a lot more (£3K+?) and I view them as too expensive rather than the Power Jack as too cheap. The £180-£250 auction range does seem very cheap especially when there are no taxes on top. The seller cannot be making much when one goes for £180. Maybe it is [url=https://en.wikipedia.org/wiki/Dumping_%28pricing_policy%29]dumping[/url]

I have no connection with the seller apart from winning one of his/her auctions.

Please let us know how it is after a seasons use.
I bought a smaller one, different company and it would not work on powersave mode for fridges. It needed a bigger draw to work. On standard mode it was very greedy of power. I have had a Marc Ting Taiwanese inverter for 2 years, it is on all season and is very efficient/economical with power. Doesn't have a charger though.
