Solar Controller 20Amp + 20Amp Dual Charging PWM
KT 20Amp + 20Amp Dual Charging PWM Solar Controller – Reliable Power, Smarter Charging
Dual Solar Controllerstay powered no matter where the road takes you. The KT 20Amp + 20Amp Dual Charging PWM Solar Controller gives you smarter, safer control over your solar setup. Whether you’re camping, touring, or working remotely, this unit keeps your dual battery system running efficiently.
Moreover, it’s designed to suit 4WDs, caravans, boats, and trade vehicles. You’ll get stable charging, advanced protection, and real-time monitoring—all in one compact unit.
Charge Two Batteries at Once with Confidence
Unlike basic solar controllers, this model can charge two batteries simultaneously. Each output delivers up to 20 amps, while the combined maximum charge is 30 amps.
This setup ensures your starter and auxiliary batteries both receive the power they need. Additionally, current is shared based on demand, giving each battery the correct charge at the right time.
Compatible with 12V and 24V Systems Solar Controller
Because it’s designed for flexibility, the controller works with 12V and 24V solar systems. It supports solar panel wattages from 100W up to 240W.
This makes it perfect for most camping, trade, or off-grid applications. Plus, it supports 48V appliances, which gives you even more options when powering fridges, lights, or inverters.
Real-Time Monitoring with LCD Display Solar Controller
One of the standout features is the LCD display, which cycles through key system stats. Thanks to this feature, you can track your system’s performance at a glance.
It shows:
-
Solar panel voltage (VOC)
-
Charging input voltage
-
Charging current
-
Battery voltage
-
Battery charging current
-
Total amp hours charged
-
Battery temperature (at intervals)
In addition, the screen clearly displays the current charging stage, so you’ll always know how your batteries are being managed.
Six-Stage Smart Charging for Longer Battery Life
To ensure optimal charging and battery health, this controller uses a six-stage charging process:
-
Trickle
-
Boost
-
Absorb
-
Float Full
-
Maintain
-
Float
Each stage serves a unique purpose. For example, the boost stage rapidly delivers power, while the absorb and float stages protect the battery’s life span.
As a result, your batteries will last longer and perform more reliably. Every stage is also indicated on the LCD, so you can follow the process in real-time.
Wide Battery Compatibility
The KT controller works with nearly every popular battery type:
-
AGM (default setting)
-
GEL
-
WET
-
Calcium
-
LTO
-
LiFePO₄
-
Li-Ion
In particular, lithium batteries require extra safety. That’s why this unit includes two 5-metre temperature probes, which must be connected for lithium compatibility. This ensures safe and stable charging based on battery temperature.
Built-In Safety Features Give You Peace of Mind
Because safety matters, this controller comes with six intelligent protection modes:
-
Overcharge protection
-
Reverse polarity protection
-
Short circuit protection
-
Working battery temperature protection
-
Reverse charging protection
-
Internal over-temperature shutdown
Even if something goes wrong, these features are there to protect your system and your equipment. For example, if the system gets too hot, it will automatically shut down to prevent damage.
Easy Setup with Included Accessories
Installation is straightforward. In fact, the clip-on/off mounting bracket and included hardware make fitting it to your vehicle or cabinet simple.
Also, the KT70574 accessory lead connects directly to both the input and output terminals. This makes wiring clean, fast, and secure.
Moreover, the user-friendly soft-touch buttons let you adjust settings quickly without digging through menus.
Designed for Harsh Aussie Conditions
KT gear is built tough, and this solar controller is no different. It operates in temperatures ranging from -30°C to 80°C. This means it can handle snow, outback heat, and everything in between.
However, it’s not suitable for mounting inside engine bays. For best performance, install it in a dry, ventilated space.
