Looks like the EPC is not something to consider. Visited the site today and got everything up and running but could only hold the generator input if we reduced the charge rate to 25%. Much higher than that and the generator sounded like it was loading down, and we had several generator faults...

The generator. Client has a 14kW gen but we are only realizing 4kW when charging. 20kW lithium bank is capable of receiving a full 140 amp charge from the XW Pro but we aren't getting it so searching for any system setting that is preventing the full charge. The gen is connected to AC2. The site...

Thanks 400. Makes sense. This is an off grid DC coupled system so in theory one would think the EPC settings wouldn't come into play but I've seen indications from others that even though it is turned off, the setting may be limiting the charge output from the XW Pro charger.

I may be experiencing the same with one of my clients. I will be there tomorrow so will check. His charging rate is throttled back and I've been struggling to figure out why. Did you ever figure out what "EPC" is. And did you access these Power Control Settings through the InsightLocal...

Thank you folks. What you say makes total sense and agrees with my take 100% on the matter. I agree completely that the ideal situation is matching everything including cable lengths etc etc but the real world does not always work that way. Concur with the "weakest link" analogy but so long as...

I have seen that it is recommended for arrays of two or more strings, that each string must have the same number of pv modules, of the same brand and model for the MPPT controller to function properly. I'm having trouble believing that this is necessary when you consider the following: At any...

Good ones do. Have a look at the Discover Blue Lithium. Field replaceable fuses
