Rolls Batteries AGM Terminal Covers to help prevent the possibility of short circuiting the batteries by insulating the terminal.

A handy device for quickly checking the level of your Rolls Batteries. Simply unscrew your regular cap and screw this one in, repeat for each cell in your battery system.

Ready-made cables for connecting batteries in series or parallel. Cables include two crimped terminal lugs.

Optimised for stringed use in large sized solar installations, Rolls OPzV Gel range is designed to maximise efficiency and cycle life, making them ideal for off-grid solar applications.

Rolls high performance S-Series Lithium-Iron-Phosphate (LiFePO4) batteries provide a compatible drop-in sealed lead-acid replacement with fast charging/discharging capability, compact case design and are up to 50% lighter than equivalent lead-acid battery models.

The Rolls VB Series 12 and 24V batteries deliver a high‑specification lithium solution at a highly competitive price point and allow direct replacement for deep‑cycle lead‑acid, AGM and gel batteries with no system redesign required.

HRSI Regulator
Uses Pulse Width Modulation (PWM) to protect battery from overcharging by tapering charge as battery becomes full and reducing the Windcharger speed. Includes LED indicators for charging status and battery voltage. Includes facility for connection of up to 160W of PV. Features windcharger shutdown switch.

The S4 RooFit Clamps are designed to securely fasten photovoltaic panels to the mounting rail or structural frame within the S4 system.

The S4 RooFit Extensions are designed to provide more flexibility within the S4 RooFit in-roof mounting system, helping adjust panel positioning and maintaining a consistent finish across the installation. This helps maintain structural stability and weather protection within the system. 

S4 RooFit Fixing Screws are designed to provide secure fastening throughout the S4 mounting system.

The S4 RooFit Flashing Hook is designed to secure side flashing components within the S4 RooFit system. It creates a stable and reliable fixing point to ensure the flashing remains in the correct position and is securely attached.

The S4 RooFit Height Riser is designed to ensure panels are correctly aligned and securing positioned when working with uneven roof surfaces.
