Solreach Residential Energy Storage(16kWh)

Q1: How is the Solreach 16KWh battery module different from the All-in-One ESS products in the range?Differentiation

The Solreach 16KWh battery is a standalone storage module with no inverter, no MPPT solar charger, and no AC output — it is a pure DC battery pack. Every All-in-One ESS model in the Solreach range (1KW to 12KW) integrates inverter and battery in a single cabinet. This battery module is purpose-built for system integrators, solar EPC contractors, and OEM buyers who already specify a preferred inverter brand and need a high-capacity 48V battery that communicates over 485-CAN. It offers greater flexibility in system design at a lower per-kWh cost than any All-in-One unit in the range.

​

Q2: Which third-party inverter brands are compatible with this 48V LiFePO₄ battery module?

The 48VDC nominal voltage (40.0–58.4VDC operating range) and 485-CAN dual-protocol BMS communication make this battery compatible with the majority of 48V hybrid and off-grid inverter platforms on the market, including Growatt SPF/MIN series, Deye SUN series, Voltronic Axpert, Victron MultiPlus, Sungrow SH series, and Must Solar. For inverters using RS485 Modbus, the 485 interface handles BMS data exchange. For inverters using CAN bus (common in European and automotive-grade systems), the CAN interface provides the same BMS telemetry. Buyers should confirm their inverter's supported BMS protocol before ordering; Solreach's technical team can advise on protocol compatibility for specific inverter models.

​

Q3: What is the actual usable capacity and what determines depth of discharge in daily operation?

Rated energy is 15KWh at 0.5C and 25°C. Usable energy at 90% depth of discharge (DoD) is 13.5KWh — the DoD ceiling is configurable in the BMS to match the inverter's cut-off voltage setting (minimum 40.0VDC). Operating at 90% DoD rather than 100% is recommended for daily cycling because it reduces lithium plating stress on the anode at full charge and cathode stress at full discharge, extending cycle life beyond the rated 6,000 cycles. For backup-only applications where the battery sits at 80–90% state of charge most of the time, a tighter DoD window of 20–80% is advisable to maximise calendar life.

​

Q4: What does IP65 protection mean in practice, and why does it matter for residential installations?

IP65 means the enclosure is fully dust-tight (6) and protected against sustained water jets from any direction (5) — one full class above the IP54 rating on the Solreach All-in-One ESS series. In residential practice, IP65 allows installation in: garages where the floor is periodically hosed down; covered outdoor battery cabinets in rain-exposed climates; utility rooms adjacent to washing machines or water heaters with occasional splash risk; and coastal environments with high salt-air humidity. For OEM partners selling into European or Australian markets, IP65 also satisfies the enclosure requirements of AS/NZS 5139 and relevant IEC installation standards for battery systems in habitable buildings.

​

Q5: How does the 200A/200A symmetric charge-discharge current rating benefit high-power applications?

The symmetric 200A charge and 200A discharge current means this battery can accept or deliver up to 10.24KW of power continuously (200A × 51.2V) — enough to supply a 10KW inverter at full load without current-limiting the battery output. For OEM buyers pairing this battery with a 5–10KW inverter, the 200A discharge rating ensures the battery never becomes the bottleneck during peak demand events such as air conditioner compressor starts, well pump surges, or simultaneous high-load appliances. The symmetric charge rating also enables fast recharge from large solar arrays or high-power grid connections without current derating.

​

Q6: What are the logistics specifications and how should OEM buyers plan container shipments?

Product dimensions: 400×260×880mm. Net weight: 103kg. Gross weight: 110kg. At 110kg gross per unit, a 20-foot container (max payload ~21,500kg) accommodates approximately 195 units. A 40-foot HQ container can carry approximately 235 units at approximately 25,850kg total payload. The wheel-type base adds approximately 80mm to the effective height during loading, which must be factored into container stacking plans — units are floor-loaded upright and cannot be stacked. All shipments require UN 38.3 lithium battery transport documentation; Solreach provides MSDS, packing declaration, and test summary as standard for all export orders.

​

Q7: Can multiple Solreach 16KWh battery modules be connected in parallel to expand total system capacity?

Yes. Multiple 48V LiFePO₄ modules can be connected in parallel to expand usable capacity beyond the single-unit 13.5KWh. For parallel battery banks, all modules must share the same BMS firmware version, cell chemistry, and state of charge at the time of connection to prevent inter-unit balancing currents. The 485-CAN communication bus supports daisy-chaining of up to a manufacturer-specified number of units (confirm with Solreach technical support for the maximum parallel count and inverter compatibility for your specific system design). A two-unit parallel bank provides 27KWh usable capacity; a three-unit bank provides 40.5KWh — suitable for larger homes, small commercial buildings, or multi-day autonomy off-grid systems.
