Dowell ipower 3kw storage inverter not powering up

[glyndwr1998]

hi all,
I picked up this Dowell storage inverter a few years back from a guy that was using it in a van to keep the back of the van cold and help keep cold vegetables to and from a market. The inverter is a transformer type, and its very heavy.
Anyhow, he gave up the business and i took the inverter off him
Its been sat around for 2 years gathering dust, i didnt test it when i got it, so this weekend, after a shed cleanout i thought id power up the brut and see how it runs.
It wont start up.
Ive put 48vdc on the battery side, and plugged in the inverter to the mains, no joy.
Removed the cover, it all looks clean inside, no signs of any burning, scorching or faulty components on the boards.
Ive put a meter on the AC connectors on the pcb and it has got 240v onto the pcb.
Has anyone got any experience in working with these types on inverters, or, if i cant get it to power up, have any use for it for parts?
Thanks
Anthony

Did you make sure the Reset button wasn't tripped?

Check the Dc voltage on both sides of the switch to make sure there's no disconnect.
What model is this unit?

Hi Korishan,
The model is ipower storage inverter 3000.
Thanks to your advice about the reset switch its now running.
The beast is running.
The reset switch was sticking, and preventing the inverter from starting up.
I think it can be set to grid or off grid, and to charge from the grid.
Now that its running i can see the menu structure, and its set to island at the moment.
Its only run for 466 kwh in total. Its hardly been used, although it looks battered as the case isnt in the greatest of shape.
Thanks for your help anyway, much appreciated.
Anthony.
