So after hearing for the last year how these units protect the RV and let you know when the campground is wired wrong I pulled the trigger and bought one. Not Cheap but if it saves me once that's all I need and since I will be recharging batteries from a generator while boondocking I thought some monitoring would be appropriate.
This has been a disappointment from the start. The biggest problem is that it doesn't fully work. The current reading never goes above 1 Amp even with my AC on so that's not right. I grab the installation instructions and they are for the 50A unit and I guess I'm expected to extrapolate for the 30A unit. The picture for the 30A unit shows the current sensor just sitting on top of the display board uninstalled - not helpful.
Here's what ticks me off, the instructions specifically state that the current sensor is to be installed with the arrows pointing at the contactor.
My current sensor has no arrows!
I'm going to suppose that they changed supplier and are using different current sense transformers abut they could have either marked them or changed the manual. Giving me a manual that doesn't match the product they shipped is very unprofessional!
So I tried the current sensor in both directions but don't get a correct reading either way.
Lastly - and I'll admit this is nit picky - would it have killed them to include two split ring washers for the ground connections? Was that a cost they couldn't afford?
Let me add that I am an Electronics Engineering Technologist with 25 years of experience repairing power circuit boards. If I have trouble with this kit then I can easily see that DIYers with less experience could also run into problems.
I would NOT recommend this to anyone without a high level of electrical/electronic experience.
