I always look for features such as ample inner spacing for components and connections. These are more expensive but also easier to maintain/or upgrade. They allow for better heat dissipation. Metal is just my personal choice, although some of the PEP types are quality units but just not as good as the steel especially when it comes to a truly solid surface mount. PowGrow has weather strip, tight closure with robust latch and hinges. Review: Well made and it works! - I have had the controller box setup out in the Florida weather (hot direct sun) for almost a year with no problems. It appears very well made with heavy wiring and solid connections. I only have three solar strings attached right now but its nice to know I can add more as I need them. I would very much recommend this box. ## Features - Professional PV combiner box is suitable for your Photovoltaic On/Off-Grid Solar Power Generation Systems.
