My main issues with Jayco's JHub System are:
(1) - The J35's AUX current output is too low for my requirements and does not match the best in class system (Enerdrive 40A).
(2) - The J35's Blended charge Algo (AUX+Solar) is in principle a good feature that would give it the edge over Enerdrive's system, but it under performs that is decides not to blend. And if you only have the Manufacturer's standard equipment installed, then you rely on every bit of charge you can get while driving in the Sunshine. The leading edge Enerdrive system is designed to be configurable to provide up to 40A from either Solar or AUX sources.
So how can we improve our JHub battery charge system ?
The BMPRO blended charging algorithm is beyond my control. It is what it is. But I did install the BMPRO Miniboost and added Solar Panels. Results below:
In my FD19's performance enhanced energy system outfit Setecs JHUB J35 with MiniBoost does typically charge my batteries with 15A in any of the 3 charge modes.
In AC mode the system powers all loads and in addition puts 15A into the battery (batteries).
In Solar mode (320W) I can now reach 20A best case, but the battery will only get the balance after all loads are supported.
In Aux mode with MiniBoost I reach typically 13..15A, but the battery will only get the balance after all loads are supported.
In Aux mode with original Jayco setup (with Redarc SBI bypass) I presume the output varies between 3..15A !
Still not good enough ?
I could have installed the Enerdrive epower 40A and
(A) fed it into the BMPRO AUX Input (will it current limit ?) or
(B) I could have bypassed the J35 and run the Enerdrive epower straight to the Battery.
That would have improved problem (1) and in case of (B) problem (2) as well.
