    Leak in solar hot water panel

    I have a solar water heating panel which developed a leak when it froze. The leak is small and at a solder joint. I can solder it but it will be difficult. Has anyone one had good results with a epoxy or other coating. The water pressure is about 75 lbs. Any information will be appreciated.

    Could you adjust load using a transformer with 240V USA standard to 120V? Check below.

    What are you trying to power and what are the ratings of the device voltage and current ?

    Solar controller not receiving voltage from panels

    You should have a voltage rating for PV2 but what I was suggesting was to connect the pv2 panel to the pv1 controller. That would be only the PV2 panel and its associated wiring. If that works it shows the controller is working. If that is the case remove PV1 from the breaker and connect PV2...

    Two SCC

    I have two sets of panels one east one west. Is there a advantage in using two SCC so that lesser producing panels don't affect the other set?

    Any UL listed solar components pls submit?

    It is required that the area below and in front of a electrical panel has to be clear for safe working access. This applies to anything not just batteries.

    Charge Controller

    Just use the solar converter to feed a battery charger. What is the three phase voltage and is it delta or WYE ?

    Solar charge controllers with a dc lead grounded.

    Looking at the epever solar charge controllers some have the negative lead grounded. What is the reason for this and why does it seem to apply only to the smaller units.

    Everybody... use safe conditions working...

    You should never allow any spot on your body to be grounded.

    How long can a car run at idle (stationary) to charge a battery bank like a Delta or two?

    If the situation is so bad that you have exhausted al other sources of power having a car with a empty tank might not be the best solution.

    AC Charger, Automatic Transfer Switch and Battery Life

    You could use a lighting controller which could be used to turn on the charger at night. This would not take care of the low light conditions but will solve the night time for about $15.00.

    M 4 solarpanel mounting connector's

    Amazon has connectors like you want. In one case there are 4 connectors mounted to a two gang box for around $45.00. You could just remove the connectors and install them in your combiner box.
