Hi everyone, please help ...
We are a van conversion company. One of our next customers is a scuba diver and will be off grid with I suppose 370W solar panel. His Sprinter 2019 doesn't have a smart alternator. He wants to have a compressor in his van to fill the Oxygen tank. He wants Victron material with about 300W solar panel and a relay charger. He will have a hook up possibility but won't have regular access. Traveling in Africa and Scotland ... extreme temperature.
the compressor that would run for about 30min every 2-3 days.
I emailed the company to have more info regarding the starting power, here tare the different answers I received.
“The start up current for the MCH6, 2.2kW 50hZ compressor is approximately 66 Amps
The compressor must be free of residue pressure, the gauge must read 0 bar before start up otherwise AMPS could be more”
“The answer is 83 Amps.
At the start, the electric motors need a variable amount of Ampere from 3 to over 5 times those written on the plate.
It depends on the type of engine and where you get the electrical power from.
I'll give you an example:
3kw 16Ampere in the house and the compressor is able to start and work.
However, if you have to use a power generator, it must be at least 8KVA otherwise it won't start.”
In top of this compressor,
electric induction hob, 12V fridge 100L, lights, laptop 4h/day, phone charging, standard 12v lights.
I don’t know which type of investor /MPPT and batteries he should use ? Plus other useful bits ...
Thanks for advising me. XX
