    iBoost goes dead and then a few days later, comes to life again

    For the last few weeks, my iboost seems to completely switch off and even if you push any of the buttons or turn the switch to the mains on or off, it does not work.

    Solar iboost not working

    We have a solar iboost which was working fine then suddenly stopped. If you turn it off at the mains and then on again, it says low voltage and heats via solar initially with a high reading then this drops until zero and it states heating off. Amy ideas on what the problem could be? Thanks

    Recharegeable batteries with iBoost

    According to the manufacturer Marlec, recharegable batteries are not recommended with an iBoost sender. Can anyone explain why please? My non rechargeables are now flat and the only spares I have currently are rechargeable batteries. Are they ok to use temporarily?

    Solar iBoost Problem

    This could prove a head scratcher. A few days ago I installed, at home, a Solar iBoost and I must say with my 3.92 South facing array it appears to work well. BUT, there is a problem and I wonder if any of you have come across one similar. The day I installed it was a very wet one. Soon after...
