Dyness DL5.0C Battery Review UK: Specs, Price & Pro Catch

The Dyness DL5.0C is a bare 5.12kWh lithium iron phosphate (LiFePO4) battery module aimed at the budget end of the UK home battery market. Like the Pylontech US5000, it has no inverter built in: your installer pairs it with a compatible 48V hybrid inverter. This review works through Dyness's own datasheet, this site's pricing, and the one thing UK buyers most need to know in late 2026 — the original DL5.0C is being superseded by a newer Pro version that is not interchangeable with it.

Dyness DL5.0C specs

The DL5.0C is a 51.2V, 100Ah module storing 5.12kWh nominal, with a 90% depth of discharge. That works out at roughly 4.6kWh usable per module (5.12 × 0.90, our calculation). Figures below are from Dyness's own datasheet (V1.0-20241011).

• Chemistry: LiFePO4, with cell-level monitoring and balancing
• Nominal voltage / operating range: 51.2V, 44.8–57.6V
• Recommended charge/discharge current: 50A (0.5C); maximum 75A charge and 100A discharge; 110A peak for 15 seconds
• Cycle life: 6,000 cycles or more, tested at 0.2C, 25°C and 90% depth of discharge
• Weight and size: 54kg; 558 × 545 × 150mm (W × D × H), wall-mounted, floor-standing or stacked
• Protection rating: IP20 — indoor use only
• Charging temperature: 0–55°C, or −20–55°C with the optional heating function
• Communication: CAN, RS485 and RS232
• Expansion: up to 50 modules in parallel (256kWh)
• Certifications listed: UN38.3, CE-EMC, IEC 62619 and CEI-021

The practical constraints are the IP20 rating and the weight. Dyness's datasheet puts the module at 54kg, so plan the wall fixing and the location with your installer. It needs a dry, indoor space such as a garage or utility room, not an exposed outbuilding. Our battery sizing guide explains how many modules a typical home needs.

Dyness DL5.0C price in the UK

This site's product listing prices a single DL5.0C at £650 ex VAT. One UK retailer, BimbleSolar, lists the original DL5.0C at £725 including VAT (£604.17 ex VAT) and marks it as limited stock and end of line, so prices vary by seller and stock. As with any bare module, that is the battery only: the hybrid inverter, cabling, commissioning and labour are all extra. Our home battery installation guide covers typical installed costs for a third-party battery plus hybrid inverter setup.

Per kilowatt-hour, a DL5.0C is typically cheaper than a branded all-in-one battery, which is the whole reason to consider it. The saving only holds if your installer is comfortable with Dyness — a cheap module installed badly is a poor trade.

DL5.0C vs DL5.0C Pro: the compatibility catch

Dyness now sells a DL5.0C Pro, and UK retailers state that Pro modules are not compatible with original DL5.0C modules. BimbleSolar lists the Pro at £949 including VAT and flags the original as end of line. In practice:

• New installs: ask your installer which version they are quoting, and why. The Pro costs more per module, so the two quotes are not like-for-like.
• Expanding an existing system: if you already own original DL5.0C modules, you may not be able to add Pro modules to the same stack. Buy the capacity you expect to need up front, or confirm compatibility in writing before ordering.
• Spares and replacements: with the original model winding down, availability of matching modules could become a long-term risk.

Warranty: check the small print

Dyness's own site says warranty terms vary by market and region and tells buyers to contact a local sales representative or authorised distributor. For the UK, BimbleSolar quotes a standard 5-year warranty, extendable to 10 years with sign-up, and this site's listing also records 5 years. European listings show 10 years. Those are not the same product promise, so get the exact term, the registration requirement and who handles claims in writing before you buy. A 10-year warranty is the norm among established brands, as with the Pylontech module.

Inverter compatibility

Dyness lists SMA, Victron, Ingeteam, Delios, GoodWe, Solis, Deye, SAJ, Voltronic and Growatt among compatible inverters, plus others. Compatibility is a per-model question, so check your chosen inverter's approved battery list rather than assuming. Our hybrid inverter buyer guide explains how to check, and the Sigenergy vs Sungrow vs Solis comparison and Growatt inverter review cover inverters you might pair it with.

Dyness DL5.0C vs Pylontech US5000

The two are close in concept: modular, indoor, low-voltage LFP modules for third-party hybrid inverters. The Pylontech US5000 is the more established name with installers in the UK, a 4.8kWh module and a 10-year warranty on this site's listing. The Dyness offers more capacity per module (5.12kWh) and, at the listed price, a lower entry cost, but with a shorter UK warranty and less installer familiarity. If the warranty term is the same in writing, the price gap is the decision; if it is not, the Pylontech is the safer buy. For a premium all-in-one comparison, see our Sunsynk L53 battery review.

Who the Dyness DL5.0C suits

The DL5.0C suits a cost-led install where your installer already works with Dyness and your inverter's approved battery list includes it, and you have a dry indoor spot for a 54kg module. It is a weaker fit if you want a simple single-vendor package, need outdoor mounting, or may expand the system later and cannot confirm which module generation you will be able to add. Whichever battery you choose, get at least two quotes from MCS-certified installers and ask each for the module version and warranty terms in writing.
