HQRP 10A Waterproof Solar Power Charge Controller / Regulator 12V / 24V 10 Amp plus HQRP UV Chain /

I installed the previous version of this unit to provide solar power to my electric garden fence on 06/04/2011. It remained in continuous use without problems for 270 days then failed. My garden is in SW Oregon, so we do get a lot of rain. The maximum temperature range during the service time was from 85F to 20F. The led tube display is completely obscured by condensation inside the unit which would tend to make me think that it was not properly sealed and in fact was not waterproof as advertised.

My advice to purchasers would be to make sure you protect the unit from rain as much as you can without impairing the necessary ventilation around the product. If you do decide to buy this product, you should probably look for a way to protect it from the rain so long as you allow proper ventilation.

I do feel that the controller I purchased was in fact faulty and should have been replaced by the supplier. They did not want to do that and their warranty is in fact 200 days.

Just be aware if you buy this controller with the intent of installing it directly exposed to the elements you should plan on replacing it in 9 months.
