Question : What types of batteries are compatible with the solar charge controller?
Answer : It is compatible with a variety of 12V/24V batteries, including Sealed, Gel, Flooded, and Lithium.
Question : Is the solar panel regulator waterproof?
Answer : Yes, it has an IP67 waterproof rating and is suitable for outdoor use.
Question : What is the maximum PV input voltage for the charge controller?
Answer : The maximum PV input voltage is 150W/12V or 300W/24V.
Question : What is the dropout voltage? If the input is 13.6v will the charger still charge to a full battery?
Answer : The dropout voltage between the solar panel and the controller is about 0.5V-0.7V. It will not charge with an input voltage of 13.6V. It needs at least 15V to charge.
Question : What gauge wire does this have?
Answer : It looks like it has 14 gauge wire.
Question : Can I use an 18 volt solar panel to charge a 12 volt battery with this controller?
Answer : Yes, you can.
Question : The description says it works with a lithium battery. How do I set the charger to “lithium”?
Answer : You need an extra wire to connect the controller and battery, like alligator clips.
Question : Is the load output energized strictly from the solar panel or does it drain the battery if no solar power is available?
Answer : When the battery and controller are connected, the load uses battery power. It has low voltage protection function and will automatically cut off at low battery voltage.
Question : My light flashes red and I have to unplug and reconnect the battery wires. Do I have a faulty controller?
Answer : The red light will flash until the battery is fully charged.
Question : I have 1 red light on 1 red light flashing and no green light. Is this working properly?
Answer : No, in normal operation, the left-hand light (PV) would be on/red if charging power is available. The right-hand light (load) would be green if the battery is available. The center (Bat) light would be bright green if proper battery power is available, bright red if a battery shortage, and flashing red if over discharge protection has been activated. Ensure proper connection and polarity.
Question : I live in Florida and the inside car temperature may exceed the rated operating temperature, should I be concerned and not use it in the environment?
Answer : It is recommended to use within the rated operating temperature to prolong the service life of the product.
Question : If I connect a 24v lithium battery, will the load also be 24v or does the load have to be 5v or 12v?
Answer : When using the 10A controller, connect the load first, then connect the solar panel. 12 and 24 volts are available for charging.
Question : Will the red solar panel light turn green when the battery is fully charged and will it maintain the battery?
Answer : It should turn green when it is charging. If it is still red, disconnect your panels and start over. Remember, there is a specific process to follow in order to charge.
