About Rolls Battery

There are 9 Rolls Battery products in the SolarBazaar catalogue, the largest share of them batteries. The listings are structured the same way for every manufacturer, which makes side-by-side comparison across brands straightforward.

All 9 listings sit in a single category, Batteries, so Rolls Battery is a focused supplier rather than a full-system brand. If you are specifying a complete installation you will be pairing these with equipment from other manufacturers, which makes compatibility checks — voltage, current and communication protocol — worth doing before you commit.

Listed Rolls Battery prices run from £ 5 to £ 1,088 (GBP), which reflects the spread between the brand's entry-level units and its largest or most feature-complete models. Prices are indicative and move with supply, import duties and exchange rates — use them to compare brands, not as a quotation.

Across those listings we hold 32 published specifications, including Storage Capacity (C10), Storage Capacity (C100), Storage Capacity (C20), System Battery Voltage and Connection. Where a manufacturer publishes a figure, it appears on the product page as a field you can compare, rather than being buried in a datasheet.

Understanding Batteries

A solar battery stores the energy your panels generate during the day so it can be used after sunset, during a power cut, or whenever grid electricity is most expensive.

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.

  • 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
  • round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid
  • communication protocol (CAN or RS485) for talking to the inverter
  • nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh)

Choosing the right battery for your system

The guidance below applies to any battery, Rolls Battery's included. Work through it against the specifications listed on this page before you compare prices — a cheaper unit that does not fit your voltages, currents or protocols costs more in the end.

  • 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.
  • Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
  • Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.

What buyers get wrong

  • Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
  • Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
  • Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.

Buying Rolls Battery in United Kingdom

Product availability on SolarBazaar is scoped by country, so this page shows the Rolls Battery range listed for United Kingdom plus any items published globally. Switching country in the header changes both the catalogue and the currency prices are quoted in.

SolarBazaar is a comparison directory rather than a shop: we publish specifications, prices and documentation so you can shortlist equipment, then buy from a local distributor or installer. That matters for warranty — cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Rolls Battery in United Kingdom before ordering.

If you are still shortlisting, BYD and Sunwoda are listed in the same category and can be compared against Rolls Battery spec by spec.

Rolls Battery — frequently asked questions

How many Rolls Battery products are listed on SolarBazaar?

9 products, spread across 1 category: 9 batteries. The count reflects what is listed for the country you are browsing, so it changes if you switch country.

What does Rolls Battery make?

Rolls Battery's listed range is entirely batteries. A solar battery stores the energy your panels generate during the day so it can be used after sunset, during a power cut, or whenever grid electricity is most expensive.

How much do Rolls Battery products cost?

Listed Rolls Battery products run from £ 5 to £ 1,088 (GBP), depending on capacity and model. Prices are indicative and change with supply, duties and exchange rates, so treat them as a comparison reference rather than a quotation.

Is Rolls Battery a good brand?

SolarBazaar does not rank manufacturers editorially — we publish the specifications so you can judge them against your own requirements. For Rolls Battery, the practical checks are the 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, and whether the warranty is serviceable in United Kingdom. A brand with strong specifications and no local support presence is often the more expensive choice over a system's life.

Where can I buy Rolls Battery products in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and prices here to shortlist, then buy through an authorised distributor or installer in United Kingdom — that route keeps the manufacturer's warranty intact, which direct grey-market imports usually do not.
