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

The Rolls AGM S Series battery range provide the performance and life of a true deep cycle battery with all the convenience of sealed construction and being maintenance free. They feature thick plates with a high density active material. This design allows for reserve energy to be stored deep within the battery plates and released during slow discharge. The Rolls AGM range are sealed, non hazardous, non spillable and completely maintenance free. They can be operated upright on their sides and are leak proof, shock and vibration resistant.

The Rolls AGM R Series batteries are an economy alternative to the red series 5. These batteries are deep cyle, sealed and maintenance free, perfect for smaller renewable energy projects.

Terminal covers protect against accidental contact & possible short circuit.

These heavy duty batteries are designed for unsurpassed repeated deep cycling service in renewable energy applications. Thick plate design with high density active material and increased liquid reserve. Several 2V cells are pre-assembled together to give higher voltage blocks. These in turn are connected to form a battery bank with appropriate voltage and capacity. Unique battery design features dual container construction. Removable cells are fitted with a durable case giving double protection against breakage or leakage. Easy on-site assembly with no special tools or skills requires. Supplied fully charged with inter-connectors. Self Discharge: ~2-3% per month.

The Rolls 4500 series combines the convenience and portability of the 4000 series, with the extended capacity and cycle life found in the heavy duty 5000 series batteries. They provide a battery with good cycle life at a great price.

Durable batteries designed for deep cycling service in renewable energy applications. Thick plate design with high density active material and increased liquid reserve. Polypropylene rigid container construction. Supplied fully charged.

RJ45 UTP (unshielded twisted pair) cables for network communications.

This is a logic module which provides system control features such as high/low voltage alarms, load control and generator start. It can drive four independent relays by reading digital date inputs from the Morningstar TriStar controller or by reading battery voltage when used in systems with other controllers. It can be DIN rail mounted and is fully programmable via RS232 port connection. Supplied pre-programmed with four commonly used settings. For use in 12 to 48V systems.

This switch shall clearly show the ON and OFF positions and be labelled as 'PV system - main a.c. isolator'.

These fuses are specifically designed to protect PV modules from reverse currents. Allows for safe circuit interruption under typical low fault conditions produced by PV arrays.

Helio DIN rail mounting fuse holders specifically designed for PV & DC applications. Rated at 1000V, 32A DC. Terminals accept up to 10 sq mm flexible cable, or 16 sq mm rigid wire. Pull out carrier to enable easy replacement of fuses.

Jumper Bar allows parallel connection of string fuse holders. Can be cut to length for use with up to 13 fuseholders.

Pack containing labels needed for a typical domestic solar PV installation.

IP66 rated enclosures with standard DIN rail for mounting fuseholders or terminals. Supplied complete with cable glands.

Terminal blocks for use with PV combiner boxes. Mount to standard DIN rail.
