I have an off grid instillation with an RD04834

i have been through two evolution controllers, i have another new one to put in (salt air is destroying them)

The last time i lost a controller i copied the settings out of the old one

Specifically pram group

i have another 0K2267C controller but the service manual has no insight as to what pram group to use besides i can chose 0 - 64

any help would be really appreciated i have guests coming tomorrow.

I don't know the answer to your question but this seems to be a common failure when these standby sets are put into prime service.

I might be tempted to convert this unit to standard industrial controls, Dynagen, DSE, Basler.

You would need at least a controller, a governor and a voltage regulator.  It might not be cheap but it might save on replacement parts.  It might not also be possible depending on how the engine is controlled.

We will need the complete model number and serial number to look up the voltage and parameter codes.

There are various types of protective spray coatings for circuit boards which will protect them from moisture and chemical (such as salt) damage.  Depending on exactly how the failure occurs, a coating may help:

Thanks everyone  I have kept them clean and protected as best I can, I think this failure might have been non corrosion, the first two were definitly corrosion. I opened this one up today and see no visible damage and probally will attempt component level repair as the error is not sense battery. In other news I got my pram group and v code from my dealer who was very helpful on a day they were closed. Thanks got the help and will consider all replies. It's not really used "prime" as its backup for my solar and only turns on on cloudy days. Ultimately it will he moved to a cleaner air environment instead of 15 feet from the sea.

Wow, 15 feet from the sea seems like a risky spot for any equipment, salt air notwithstanding.

Sometimes, one of the bigger challenges of installs is finding a spot for the generator on a tight lot.  I could see that happening.

I met the unit in that spot when I took over a few years ago, the thing is logistics can be hard when you dont want the guests to hear the unit if it turns on at 5am when the battery voltage drops, also further from the dock is further for diesel to be moved etc. We now have heavy equipment and a new utilities room to put the unit in and use the equipment to move the fuel. So I hope the unit enjoys a new lease on life in it's new home
