LED indication for Equalization Cycle on a Wanderer 30A Controller
I have the Wanderer 30A PWM Charge Controller that came with an Amazon 100W Solar Kit Bundle.
The manual does not identify any PV/Batt indicator light combination which represents the normal function of the periodic "Equalization" charge mode. Nor does the Status Troubleshooting section describe the function as normal as opposed to differentiating any otherwise adverse condition of ’over-voltage' or 'over-heating' outside the cycle. Neither can I find any indication of whether the unit is 'programmable' vs auto / self-regulating.
I have no idea what led indication pattern might be related to the 'Equalization' cycle vs adverse conditions and no control over when it happens, so how am I supposed to 'make sure' the battery is in a no-load state during, or know when the cycle is active so that it may be properly monitored?
What light pattern indicates the cycle end?
The 2 FLA batteries are new. Would the controller even use this cycle yet?
At this point I’m afraid to leave the system on without babysitting it.
Twice already, I've encountered the PV led flashing fast with PV input voltage at around 20v at the controller terminals. This does not exceed the max 25V PV output, but does exceed the normal specs of a 14-16V operating range, including the Equalization cycle, while showing a throughput out to battery holding at 14.5ish.
Not sure what’s happening, I used a manual disconnect to cut current from the PV to the controller and have to touch the controller button to stop the led from flashing.
Is that the Equalizer cycle operating that I truncated, have I cancelled an adverse condition, or is it just normal because I cannot tell from the manual’s treatment of LED flash combinations.
