Residential and villa backup
Whole-home backup and solar self-consumption where a single floor-standing enclosure is preferred over multiple wall units.

51.2 V floor-standing cabinet · B2B and OEM supply
Model: LD 48314
The entry cabinet in the LD deep-cycle range. A narrow 250 mm footprint makes it the practical choice where floor area is the constraint — plant rooms, retrofit basements and villa utility spaces — while still delivering 16 kWh per unit and scaling to 15 units in parallel. Communication is CAN, RS485 and RS232 for closed-loop operation with mainstream hybrid inverters, and cycle life is specified at 6,000 cycles under stated conditions of 25 °C and 80 % depth of discharge rather than as an unqualified headline number.
No public price. Quotation is based on model, quantity, application, customisation and delivery requirements.

Buyer decision points
This page is structured around technical review, procurement qualification and project conversion rather than retail pricing.
6,000 cycles is specified at 25 °C and 80 % depth of discharge. A cycle figure quoted without temperature and DOD is not comparable to this one. If your site runs consistently warmer, ask for the derating position before you specify.
This cabinet is rated IP20. It is not suitable for outdoor mounting, unprotected carports or wash-down areas. Match the rating to where the unit will physically sit — an outdoor install on an indoor rating voids the warranty and creates a safety risk.
Recommended 100 A · continuous maximum 100 A recommended / 200 A max.
Deye, Solis, GoodWe, Growatt, Sofar and SMA are supported at brand level, but protocol and firmware vary by model. Send the exact inverter model and firmware version and we will confirm the CAN protocol setting before shipment.
Up to 15 units in parallel
Recommended continuous current is 100 A with a 200 A maximum. Size the system against the recommended figure for sustained duty and reserve the maximum for short-duration peaks.
Protection rating: IP20
Pack-level documentation covers CE, MSDS and UN38.3. IEC 62619 and UL 1973 are held at cell level. These are different scopes — if your project or AHJ requires system-level listing, raise it before ordering so we can confirm what is and is not available.
Net weight is ≈ 120 kg and package weight is ≈ 137.5 kg. Confirm lift access, door widths, lift capacity and floor loading at the installation site before delivery is scheduled.

Application fit
Positioned for distributors, solar installers, EPC contractors and OEM brands specifying floor-standing storage into residential, light commercial and off-grid projects.
Whole-home backup and solar self-consumption where a single floor-standing enclosure is preferred over multiple wall units.
Shops, clinics, workshops and small offices covering evening peak tariff periods and short grid outages.
Farms, lodges, remote housing and telecom sites where grid supply is intermittent and daily cycling is the norm.
A single 51.2 V platform across three capacities, so a distributor can cover a capacity range from one technical document set.
OEM / ODM capability
This platform can be reviewed for private-label projects and system-integration requirements. Optional functions should be defined before sample production and locked after approval.
Share target quantity, market, application, inverter model and charging profile.
Confirm cell configuration, BMS, communication protocol, enclosure and document scope.
Review label, packaging, firmware and functional requirements before mass production.
Assembly, functional testing, aging and final quality checks against the approved configuration.
Prepare lithium battery export documents and the agreed export packaging.
Supplier verification
A B2B product page should let a procurement team verify who builds, tests and supports the battery. Safecloud Energy Inc. was founded in 2007 and operates two plants in Henan and Anhui, 48,000 m² in total, with eight automated production lines, 30+ aging machines and an in-house testing laboratory.
Verify cells, BMS, enclosure, wiring and purchased components against the approved configuration.
Check voltage, current, capacity, protection functions and communication against the inspection plan.
Run configured packs through defined charge, discharge and communication cycles before release.
Confirm firmware, label, terminals, accessories, manuals and carton marks.
Protective packaging with the project-approved pallet or carton arrangement for the agreed route.
Buyer questions
It is specified at 25 °C ambient and 80 % depth of discharge, with end of life at the stated capacity retention. Those conditions are part of the specification, not a footnote — a cycle figure quoted without them cannot be compared with this one.
No. It is rated IP20 and is for indoor installation in a dry, ventilated space. For outdoor projects, tell us the site conditions at quotation and we will advise on an alternative enclosure.
Mainstream hybrid brands including Deye, Solis, GoodWe, Growatt, Sofar and SMA over CAN, RS485 or RS232. Protocol selection is model-specific — send the exact inverter model and firmware and we will confirm the setting rather than asking you to trial the menu.
Up to 15 units. For multi-unit installations, confirm total current, busbar and cable sizing, protection coordination and address settings for the specific project before commissioning. This model is rated IP20.
UL 1973 is held at cell level, alongside IEC 62619, CE and RoHS. Pack-level documentation covers CE, MSDS and UN38.3. These are different scopes and we state them separately rather than combining them into one certification list.
Model code, quantity, destination market, inverter brand and exact model, parallel quantity, ambient temperature range, expected cycles per day, and any OEM branding or optional functions. For this model: 5 years / 6,000 cycles, to 70 % capacity retention.
