Overview

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. 4300 cycles to 50% DOD 2750 cycles to 80% DOD 5 year warranty The Rolls 5000 Series now come with: Free Water Miser battery caps - for reduced water loss Free Interconnection leads Free Nut and bolts Free Terminal caps Free Delivery to most of the UK mainland (for orders of 2+ units)

What these specifications mean

Rolls 5000 Series is listed with 6 published specifications from Rolls Battery, including system battery voltage of 12V, storage capacity (C100) of 479Ah, storage capacity (C20) of 371Ah and storage capacity (C10) of 330Ah. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a battery, the figures that matter most are system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Choosing a battery: the checks that matter

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.
Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.

Where buyers lose money

Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.

Price and availability in United Kingdom

Rolls 5000 Series is listed at £ 1,088 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Rolls Battery locally before ordering.

Rolls 5000 Series — frequently asked questions

How much does Rolls 5000 Series cost?

Rolls 5000 Series is listed at £ 1,088 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

We hold 6 published specifications for this battery, including system battery voltage 12V, storage capacity (C100) 479Ah, storage capacity (C20) 371Ah, storage capacity (C10) 330Ah and connection 8mm Flag. The full table is on this page, listed under model RB-12CS11PS.

Who makes Rolls 5000 Series?

Rolls 5000 Series is a Rolls Battery product, listed under batteries with model reference RB-12CS11PS. The Rolls Battery brand page lists the rest of its range so you can compare across the catalogue.

Is Rolls 5000 Series right for my system?

That depends on what it has to connect to. For a battery, check system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 against the rest of your equipment before price enters the decision. Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.

Where can I buy Rolls 5000 Series in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
