Can it withstand having the battery disconnected if the solar panel is attached and generating voltage?

I don't think so caused by checking battery not yet full ( show picture in controller )

Hello I believe you may unhook the batteries any time, as the same happens when the battery is full, it automatically shuts down, Thanks John

battery is connected the solar power also connected to normal position for charge , but at least 1 week some time 5 day the control is hang even touch any key display not change , but after disconnect battery and connect again display active it's stating to working normal.When automatic shutdown we need to restart ? or start up automatically ?

The voltage from solar is normal 15v to 18v caused the panel is 80w , I following to check it's hang during normal voltage charge at 13,8v , but after reset ( disconnect the battery ) back to working normal .

Yes, it's like closing off the nozzle on a guarded hose - the pressure is still there (voltage) but the current flow is stopped. The battery stops charging when it's float limit is reached so that it won't boil off a wet cell battery. If the regulator couldn't handle the panel's charge potential then it would burn out once the battery reached full charge. One caveat however, the unit might require a battery to complete the hookup for the screen display.If it's a temporary battery exchange, I would disconnect one of the panel wires going into to the CM30 as well and install a fuse or switch on the solar panel side just to be safe.

I dont know. I have only used mine once when the electicity was out. I haven't even tried charging mine with the solar panel. I keep it plugged in.

There is an "On" setting. If the Solar Panel is in direct sunlight then I'd assume that the light would stay on for quite a while.

You should NOT connect directly to a solar panel.... you should go thru a charge controller to regulate voltage, and to cut it off when solar panels do not generate enough current/voltage...

I've had mine about 3 years and the solar panel works great as a power source. As for recharging rechargeable batteries, doesn't SEEM as effective.

Its only a 5 Watt panel so no. Running something from a solar panel, without a DC battery, isnt practical anyway if you need any sort of a constant voltage.

Of course friend, the panel is high efficiency, full sun generates 22 volts, you need a charge controller 12 Volt so you do not overload the system, it will keep you charged and when the battery is charged, disconnect, which prevents damage to your batteries!

Yes, you can keep connected and keep the battery charged as long as the solar panel is also installed, I use it daily to keep my batteries charged and mew so far has given excellent results
1298025
Yes. Just keep it plugged in 24/7 and you wont have to worry about the battery going dead or having to reconnect it.
596203
Yes it could stay connected long term without harm. As for starting I would have unplug just in case the amp draw is to high but this is pretty cheap cost wise so worth a shot. Don't forget your solar panel 40w at least.

I do not believe that this is possible, though I could be wrong. I was under the impression that this requires a bit of skill, perhaps a designated solar breaker, etc. The battery required, would be a solar battery (deep cycle battery). You would wire this from the panels to a solar charge controller, battery and an inverter.

Yes, I use a large panel at home and it can fully charge the batteries in about two hours in direct sunlight. I have a small 40watt panel that I used out in the field and it kept my ham radio running all day without a decrease in stored battery power.

i have 28W solarpanel which produces voltage between 15 and 21V depending on sunlight. Can this battery be charged with variable Dc Volt from the solar panel? will it damage battery ?

it gives off energy that goes to a battery that goes to whatever you have hooked up to it. but make sure you stabilize it so that it doesn't break. one crack and the whole thing cracks up. and it will lose a lot of the effectiveness. don't bother with the module that you can buy with the panel, it doesn't work very good and I'm going back to the simple module that I got with my panel I bought at pep boys.

It will go off all by itself after a short time. It is solar, so no worries about a battery running down.

It has been my experience that it is best to disconnect the battery once it is fully charged. I don't think it will be unsafe, just not good for the batteries.

Not meaningfully. The panel is good for slowly (day or two, maybe three) recharging the battery after use, and maintaining the charge between uses. By itself, it would barely turn the motor, and there'd be the added complication of keeping it aimed at the sun.
