These are infinitely better than expensive grid tie arrays. Easy install just plug and play. Ive actually got 700 watts up in series-parallel. My roof pitch faces east and west so I have 3 to catch the morning sun and 4 to catch the afternoon sun. Working great the voltage is about maxed out around noon in the summer but I think the mppt keeps it low enough. Got it hooked up to a 400ah battery. Powers a 6000btu window ac all day or a 500 watt space heater for several hours a day in winter. Also have a charging station and wifi it runs. Electric bill is $100 less per month. The mppt is really great. It will charge even on the cloudiest days. Very handy during 2 power outages already. For the money the value is unbeatable.

We added a few more solar panels, another array for our small power station. These cables fit and worked just right. We were very happy with the quality.

Would not detect solar panels accurately, and instructions/ user interface is nonsensical.

What I really like about this battery is it has a warmer and also is similar to a regular battery size.
It performs just as expected. The company also has wonderful and fast customer service.
I definitely will buy from them again.

good

I have 4 of these 175W Renogy panels on my Campervan and they are working fine. I bought them after being satisfied with 4 of their 50W panels. That experience showed me that you rarely get more than half the rated wattage, and usually around a quarter. For that reason you have to have lots of panels. It's really satisfying when they work well.
