New XTRA series - 3rd Generation MPPT
For 12V Solar System: 390W solar panel (150V for max input voltage)
For 24V Solar System: 780W solar panel (150V for max input voltage)
No Fan for silent operation, great for vans, boats or any live in spaces
With built in LCD advanced display and programming screen (XDS2)
New XTRA series has Lithium battery support (set via PC cable only)
The XTRA tracer models have a current limiting function, you can connect twice the rated power to the controller so if your on a budget you can use a smaller controller with more panels so that you get more power in winter or low light but don't risk overloading the controller in the summer. The output will be limited to the max listed above.
New EPEver (Tracer) series is EPsolar’s third generation of MPPT controller.
XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off grid photovoltaic systems, with display unit.
In order to maximise the energy harvest from PV arrays and simultaneously minimise the power loss within a wide range of operating conditions, XTRA series apply an advanced smart algorithm which results in up to 30% higher efficient charging, compared to a conventional pulse width modulation (PWM) charge controller. Xtra series controller have limit protection function on charging current &charging power, as well as auto derating power operation at high temperature; the above protection ensure the stability of system even at exceeded rated PV power and over temperature conditions.
Protection class IP32 and isolated RS485 communication port further improve the controller’s reliability under different application requirements. XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which eeffectively prolongs the lifespan of battery and significantly improve the system performance. It also has extensive electronic protection for overcharge, over discharge, PV&battery reverse polarity and etc. to ensure the sustainability and durability of the o-grid solar system.
¹ If using Lithium battery, customer should use “PCsoftware” to set the lithium battery parameters

A pair of 2mm stainless steel (316L) solar panel brackets designed with canalboats and vehicles in mind, supplied with marine standard cable glands and anti tamper bolts & bit.
Allow your solar panels to both tilt and swivel throughout the year, maximising the sun's energy whilst providing excellent ventilation. This can improve the power of your panels by up to 40%, perfect for smaller systems where efficiency is key. *Standing at just over 25cm high and 16cm wide they're designed to maximise the angle of your panels whilst being low enough for most bridges and tunnels.
Using any padlock attach your panel securely to the roof via an integrated 8mm stainless steel chain that secures directly to the bracket, keeping your panels safe. The anti tamper bolts secure the bracket to your roof for maximum security deterring even the most determined of thieves.
Using M10 for both bolts and glands means you only need to drill six identical holes, saving both time and money on tools or labour whilst providing a safe and secure mounting solution.
A tool kit with everything you need for a waterproof and secure installation supplied separately, select the tool kit option to purchase this as well.
2 top spec cobalt drill bits and M10 tap and ratchet allow quick and easy installation with even the toughest steel roof. Supplied with marine sealant and instructions, a secure and waterproof installation can be done in as little as 4 hours.
Save yourself hours of drilling! Get our essential toolkit for installing the boat swivel mounts!
