FAQ

The J35B-L does not serve as a DC-DC charger. We offer the MiniBoost, which is a DC-DC charger that can connect to the J35B-L.

The J35B-L features an in-built solar regulator. You can connect the positive and negative leads from your an unregulated 12V solar panel directly to the solar input on your J35B-L.

If you have a regulated solar panel, it cannot connect to the J35B-L. It must be connected directly to your battery.

The solar card within the J35B-L will limit the maximum input to ensure your batteries do not become overcharged. If is safe to have solar system that can produce slightly more power than the maximum solar input on the J35B-L. If the watts are exceeded, it will shut the solar down for approximately 2 minutes. Then, turn it back on once the wattage has dropped back under the input.

    I’ve had an expanda since 2017, and whilst the tablet has died we have enjoyed the unit.

    I am looking at replacing it with J35B-L, and a new control node with tablet, is this unit a direct replacement?

    I think I will replace my entire system with something better. My system is not reliable and I cannot operate my Sphere fridge that came with my J-Pod on the battery. From day one, the fridge temperature rises quite quickly. On cold days it settles at around 8 degrees C and when the days are warm to hot the fridge temperature rises to around 15 degrees C. I assume that my battery is not taking a proper charge. The solar -panels are a joke as they don’t seem to have any effect on the charging of the battery…not even after a full day in the sun. Last weekend I was reading in bed with only the bedside light on when the system shut down leaving me without any power. Because of other campers in the vicinity, I was unable to start my generator.
    After about eighteen weekend outings, and despite the generator running during the day, the system is most unreliable when on 12 volts DC in the evening.

    Shame the VOC is so low. All my 250W panels are well above this.
