Review by AxxxN (NZ)
Fast shipping. Controller works OK with all the features as described except for the; Amp and Amp-hour display won't work. The battery output is quite smooth, without the desulfation spikes that I would like to have during Pb battery charge mode. Other controllers I have purchased for this price have this type of output. Also, the power semiconductors have their heat sinking contact on the rear panel which is only very light steel. This could be better ( heavier alloy) for the 30A version. The USB outputs work well and the other terminal connectors are big enough.

I have 12v 8aH batt and 12V 20W panel. Which model is suitable ?

8 aH batt için 10 aH yeterlidir ama 20 aH modelini alsan da sorun olmaz daha iyi olur iyi günler.
