The IT-NC G3 series is a new generation of high-current MPPT charge and discharge controller. It features load output capability and delivers superior MPPT tracking and conversion efficiency. The series is compatible with various lithium battery types and supports three-stage charging management to extend battery lifespan. Its exceptional low-power design significantly reduces static consumption, prolonging system standby time. Comprehensive electronic protection and flexible communication options (WiFi, Bluetooth, 4G, etc.) further enhance system reliability and monitoring capabilities. It is widely used in RVs, boats, industrial monitoring, and small to medium-sized solar power systems.

Boat Solar Panel Tilting Mounting Bundle - Stainless Steel Swivel Brackets

A pair of 2mm stainless steel (316L) solar panel brackets designed with canalboats and vehicles in mind, supplied with 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.

Why Orange?  Why no Red & Black options...

We only sell loose orange weld cable which is better than the red or black alternatives. It's top quality tinned copper cable, you need to accept the colour of the sheath or heat shrink over it. The benefits of tinned copper is better conductivity and much great corrosion resistance for marine and mobile applications.

In addition, our battery cables are manufactured in accordance with BS 638 Part 4 & EN 50525-2-81. It has a rubber compound to achieve the 85deg temp rating to meet all the requirements of EM5, that allows the cable to achieve the increased current carrying capacity.

Inferior cable has PVC instead of rubber and can only achieve a 70deg temp rating, which suggest a reduced current carrying capacity and inability to meet EM5 standards.

Fitted with Staubli 4-6mm MC4s - Staubli MC4 Link

Wire size range: 6mm2

Ideally 6mm solar cable max - for bigger units with bigger cable click here

Unit best used for housing 1 x AC RCBos, string fuse holders and fuses up to 32a as opposed to DC Din Mount breakers.

Best practice would be to use this unit with no bigger than 6mm square cable and appropriately sized breakers if you are using it with glands for a water tight fit.  If you are using it in an environment that is already dry and dust free the use of glands may not be necessary.

This is an empty unit, you must add the breakers you need to your cart as well, see related items tab above to see the breakers that fit.  

You will also need suitable cable entry glands - please see related products tab.

Protect your off-grid or grid tied PV system from unexpected string faults using Mersen’s HelioProtection® fuse line

Developed specifically for the protection of PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated fuse is designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays.

The 10 X 38mm fuse can be used standalone with the DIN mount string fuse holder to fuse a single circuit or as a bank of fuses in a solar combiner box.

This item fits String Fuse holder
