Waterproof 20A 12V/24V solar charge controller / regulator for caravans, motorhomes, campervans, boat, yacht and marine applications

Ensure uninterrupted power for all your journeys with the Waterproof 20A Solar Charge Controller. Designed specifically for caravans, motorhomes, boats, and marine use, this robust regulator vigilantly protects your batteries while maximizing their charge. Experience the freedom of worry-free off-grid living, knowing your power system is secure, efficient, and built to withstand any weather.

Here’s what makes this solar charge controller an essential addition to your mobile or marine power setup:

• Protects Your Batteries: This controller keeps your batteries safe. It stops them from over-charging or running too low. It also prevents power from flowing back to the solar panel at night, so your battery holds its charge.
• Smart Charging (PWM): Our controller uses PWM technology. This helps your battery accept charge better, making it last longer. It can even help bring back some lost battery power.
• Totally Waterproof (IP67): No worries about water here! With its IP67 rating, this controller is fully sealed. You can use it safely in any weather, perfect for boats, RVs, and outdoor use.
• Works with All Battery Types: This smart unit works with both 12V and 24V systems automatically. It supports common battery types like sealed, gel, and flooded batteries. Simpler controllers often only handle one type.
• Handles Strong Solar Panels: It can manage a lot of solar power. Connect up to 320W of panels for 12V batteries, or 640W for 24V batteries. This is great for small or medium solar systems.
• Accepts Many Solar Panels: You can use solar panels with voltage up to 50V. This means it works with standard off-grid panels and even higher-voltage on-grid panels, giving you more choices.
• Full Safety Built-In: This controller has many safety features. It protects against over-charging, over-discharging, too much load, short circuits, and overheating.
• Easy Monitoring & Control: You can keep an eye on your system and change settings in a few ways:
  
  • Remote Screen (MT50): Connect an optional MT50 screen to see what's happening and adjust things. (Needs a special cable.)
  • Wi-Fi App: Add an optional Wi-Fi module. Then, you can use a free app on your phone or tablet to check and change settings wirelessly. (Needs a special cable.)
  • PC Connection: Hook it up to your Windows computer with a USB cable. A free program lets you monitor and change settings from your laptop.
  With these options, you can check battery voltage, current from panels or to loads, battery charge level, energy used, and more. You can also customize battery settings, charging times, and even set timers for things like lights or fans.
• Better Charging by Temperature: It has both an inside and outside temperature sensor. This helps it charge your battery perfectly based on the surrounding temperature.
• Clear Status Lights: Simple LED lights show you if it's charging, your battery status, and if your loads are working.
• Manage Your Power (Loads): Use its dual timer and different load modes to control your connected devices smartly.
