Thank you Bob and Deb,
It's amazing what one finds when looking for something else. The more you look, the more you find!
I also received a response from Net Meter Solar
regarding whether or not the parameters can be adjusted. as stated in their listing. They confirmed that they can not
be adjusted. The up and down buttons are only for scrolling through the menu.
They seemed to be fairly knowledgeable about solar
systems and didn't feed my a line, so it occurred to me to asked them about the use of my Honda 1000w generator
to recharge the battery
if the weather was bad and not sufficient charging from solar panels, and if the charging would damage the controller.
Their response was:
Regarding the subject of external charging source our experience has been mixed. We have some customers who have reported problems with the unit operating in RVs and have the AC power hooked up which damaged the controller. But we also have other customers that have been using it that way with no reported problems.
If you put a disconnect switch between the battery and controller that would definitely do the trick. But if you are going to do that I would recommend you getting a STDP switch and disconnect both the battery and solar panel from the controller at the same time. You only need to disconnect the positive of the battery and the positive of the panel by connecting them to each set of pins. The switch would have 4 pins with two set of isolated switch lines. It would not be good to have a charge controller connected to a panel with no battery.
What is your intended use for the system? What is the load and how many panels are you going to have?

Wow, so it looks like any other charging source whether from a generator
, shore power with converter & charger, or power line from tow vehicle could damage some solar controllers.
Has anyone had any experience or heard anything about this?
I contacted Renogy regarding their PWM30LCD controller. Their manual says, and they confirmed it in a phone call, that the battery can be charged
with a generator
with no damage to the controller. Looks like that's another issue to be checked before buying a controller.
