48V 55A MPPT Solar Energy Charge Controller Working Voltage DC150V 12V 24V 48V Auto Max PV Input 3000W for Selectable Batteries

本物のMPPTで発電効率がとても良い。12～48Vバッテリーまで対応しているのも使いやすくて◎ 。サポートも迅速丁寧なので故障時にも安心できると思われる。耐久性もファンが付いているので自然冷却の物より長そうである。ただしファンの音は少し五月蠅い。

Estoy muy contento con el. Es muy bueno. No a fallado. Solo estoy inconforme porque no se le pueden apagar los leds. Están encendidos noche y día. Atrae muchos insectos. Y si se cubre con una malla de sobrecalienta.

しっかりした造りで、確かな価値観を感じます。

45 Aタイプで300wパネル4枚接続行けました。 バッチリ発電してます。

I had this controller installed in an off grid installation for 6 months before doing this review. I will start with the bad! - High standby draw at night (like 30W compared to 5w for brand name controllers). Think about that, its like having 6 5W LED bulbs on all night! - You cannot adjust the voltages. It is stuck at what the manufacturer determined was correct and its too low for FLA batteries (especially in a cold environment). - The interface is super poor (not laid out well) - The manual is laughable and they don't tell you the password (not that it does much good as there isn't much you can change. - ITS HUGE in size compared to brand name controllers with similar specs. The Good! - It does have a decent MPPT algorithm - Build quality is decent. Good solid terminals and a nice solid outer case. I have now removed it from my system and replaced it with a well know brand. Yes, that brand costs more, but its worth every penny. You get more features (bluetooth), more flexibility, better support, ect ect. My advice, skip this product and spend more on the big brand. You won't regret it. My batteries are now getting charged to %100 at the right voltages!
