Stores midday PV output for evening use where the inverter supports a 48 V DC-coupled battery.
Wall-mounted home energy storage · B2B project supply
Models: FT-48100 · FT-48200 · FT-48300
Three capacities on one wall-mounted 51.2 V platform for residential solar self-consumption and backup. RS485 and CAN are available for inverter integration, and up to fifteen units can be paralleled for larger installations. The metal enclosure is designed for an indoor wall in a plant room, garage or utility space.
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.
This page covers a whole capacity range. Quote against a single model code so the terminal, enclosure and current rating on your purchase order match what ships.
Charging must not start below 0 °C; the BMS blocks it to protect the cells. Discharge continues to -20 °C. For cold markets, ask about the self-heating option before you specify.
Recommended · continuous maximum 100 A
Provide the exact inverter brand and model. CAN or RS485 protocol, cable pinout and firmware version should be verified on the bench before sample approval.
Up to in parallel
Review total current, busbar and cable sizing, protection coordination, address settings and topology for the specific project.
Protection rating: IP20
This range is rated IP20. Match that to where the battery actually sits — an indoor rating on an outdoor install voids the warranty and creates a safety risk.
Confirm which pack-level and cell-level certificates apply to the exact production configuration and target market before publishing or purchasing.

Application fit
Positioned for distributors, system integrators, installers and OEM brands specifying batteries into their own systems.
Stores midday PV output for evening use where the inverter supports a 48 V DC-coupled battery.
Sized per circuit set: 5.12 kWh for essentials, 15.36 kWh for whole-home in most European and Australian homes.
One wall bracket and one protocol set across three capacities, which keeps installer training and stock simple.
Branded enclosure, label, packaging and protocol configuration for regional brands.
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, load and charging details.
Confirm battery configuration, BMS, terminals, housing and documents.
Review product label, packaging and functional requirements.
Assembly, functional testing, aging and final quality checks.
Prepare lithium battery shipping documents and agreed packaging.
Supplier verification
A B2B product page should help procurement teams verify who will build, test and support the battery. Safecloud Energy Inc. was founded in 2007 and operates two plants in henan and anhui, 48,000 m² total, with eight automated production lines, 30+ aging machines, in-house testing laboratory.
Verify cells, BMS, enclosure, wiring and purchased components against the approved configuration.
Review voltage, current, capacity, protection functions and communication according to the inspection plan.
Run configured systems through defined charge and discharge and communication checks before release.
Check firmware, label, terminals, accessories, manuals, carton marks and project-specific details.
Protective packaging with project-approved pallet or carton arrangement suitable for the order and route.
Buyer questions
Start from the load, not the capacity. Send the continuous and peak current, the daily energy requirement and the autonomy you need, and our engineers will map that onto a model code before quotation.
RS485 and CAN interfaces are provided, but compatibility should not be assumed from the brand name alone. Send the exact inverter model, its protocol document and the cable pin definition so we can review it and bench test the pairing.
No. The protection rating listed in the specification table is intended for protected indoor environments. Mount it on an indoor wall with clearance for service access and heat dissipation, away from rain, condensation, corrosive atmosphere and uncontrolled heat.
No. Bluetooth, display, communication modules and low-temperature charge protection are options. Confirm what you need during quotation so the BMS, enclosure, wiring and documentation are configured accordingly. This model is rated IP20.
Model code, quantity, target market, current requirement, optional functions, logo or label files, documentation scope, target delivery time and application details.
The warranty term is stated in the commercial section of the specification table. Warranty handling, spare-part supply and RMA turnaround are agreed per distribution or OEM contract, and depend on the installation staying within the stated temperature and current limits. For this model: 5 years / 6,000 cycles, to 70 % capacity retention.
