Intelligent solar charge controller designed to maximise energy harvest, protect batteries, and simplify system monitoring Key benefits - Increased energy harvest: Built-in optimization algorithm boosts charging efficiency by 15–20% versus conventional controllers, with a peak efficiency of 99.9%. This captures more solar power from the same array. - Longer battery life: Intelligent charging stages plus temperature compensation reduce battery stress and extend service life for gel and lithium batteries. - Reliable operation and safety: Multiple protections prevent damage from over-temperature, short circuit, and reverse polarity. IP21 rating allows reliable indoor or sheltered outdoor use. - Easy to use and install: Automatic 12V/24V detection, a clear LCD for status and fault diagnostics, and a compact footprint make installation and daily use straightforward. - Device charging on the go: Built-in USB output (5V/3A) provides convenient power for phones and small devices. Features and what they mean for you - Intelligent charging regulator with built-in algorithm - Optimises charging profiles for higher energy conversion and faster stable charging. - Automatic 12V/24V system detection - Fits both 12V and 24V battery systems without manual switching. - Battery compatibility - Supports common battery chemistries such as gel and lithium. - Maximum solar input power - 240 W maximum at 12 V systems - 480 W maximum at 24 V systems - Comprehensive protection functions - Over-temperature protection, short circuit protection, reverse polarity protection help prevent costly failures and downtime. - Environmental protection - IP21 rated for protection against vertically dripping water and typical indoor/sheltered outdoor environments. - User interface and convenience - LCD display for easy system monitoring and fault detection. - USB output (5V/3A) for charging mobile devices. - Compact size - 130 x 130 x 58 mm for convenient mounting in tight spaces. Practical use scenarios - Off-grid cabin or remote shed (12V) - Pair with a small PV array and a 12V gel or lithium battery to improve daily energy capture, monitor the system on the LCD, and charge phones from the USB port. - Campervan or RV system (12V or 24V) - Automatic voltage detection simplifies integration into either 12V or 24V vehicle electrical systems. Built-in protections guard batteries and wiring during travel. - Small commercial or telecom backup (24V) - Use with a 24V battery bank and solar array to maximise available solar input (up to 480 W) while protecting batteries and allowing quick fault diagnostics.
