Q. Will the SE-135/150 keep my vehicle battery charged?

A. The SE-135/150 battery maintainer compensates for natural voltage losses and key-off small instrumentation drain by replenishing 0.675 AH/day / 0.75 AH/day, to your battery or battery bank at a maximum rate of 135mA/150mA in full sunlight.

Q. What types of battery can I charge?
A. You can trickle charge all types of 12V batteries with these solar chargers (SE-135 & SE-150), including lead-acid (automotive), deep cycle (traction type), gel-cell batteries, also AGMs and heavy-duty (stationary type) batteries.

Q. Can the SE-135/150 drain my battery at night?

A. No. All Sunsei(tm) solar panels are equipped with a built-in diode, which prevents any reverse current.

Q. Can I overcharge my battery with the SolarCharger SE-135/150?

A. The SolarCharger SE 135/150 will not overcharge a standard 12V deep cycle vehicle battery. However it could overcharge batteries with less than a 40.5AH/45AH capacity. We recommend the use of charge controllers for batteries with smaller capacity.

Q. Can the solarcharger SE-135/150 be left outdoors?

A. Yes, however we suggest that you put a bead of clear silicone gel around the edges of the solar plate and connector. If the panel is going to remain outside permanently we suggest you place a protective cover so that the water does not hit the panel directly.

Q. Can I start my vehicle with the SE-135/150 connected to the cigarette lighter socket or battery?

A. Yes. The SE-135/150 can remain connected while the vehicle is operating. As a safety precaution while driving, store the panel in a secure location.

Q. Will the SE-135/150 always charge the battery through the cigarette lighter socket?

A. In some car models, the cigarette lighter socket is inactive while the vehicle is off. Please consult your car owner's manual. In the event that your car presents this limitation, use the battery clamps wire provided with the unit in order to connect it directly to your battery.

Q8 When I push the test button, the LED does not light up on the SE-135/150.

If the LED is not lit when pressing the test button, it may mean you are not exposing the unit to enough daylight. Please position the solar panel to maximize its exposure to the sun. If this does not trigger the LED to work, it is possible that the LED is burnt out. The LED may have a more limited life span than the panel, but this in no way reflects on or affects the performence of the solar panel. You may test the voltage and amperage with a multi-meter to confirm that your panel is working.
