Description
51.2V 230Ah LiFePO4 Battery Wall-Mount: overview
The OSM 51.2V 230Ah LiFePO4 Battery Wall-Mount is a 51.2 V / 230 Ah rated wall-mounted LiFePO4 home battery, storing about 11.7 kWh of nameplate energy. It is engineered for home solar self-consumption, whole-home backup and off-grid living.
LiFePO4 (lithium iron phosphate) chemistry is the reference choice for this duty because it is thermally stable, keeps a flat voltage curve across most of the discharge, and tolerates daily deep cycling without the capacity walk-down that lead-acid suffers. The pack is assembled around Grade A cells and managed by a battery management system that enforces the published voltage, current and temperature limits from the factory.

Sizing this wall-mounted LiFePO4 home battery for your project
51.2V 230Ah LiFePO4 Battery Wall-Mount stores 11.7 kWh per pack. For a rough bank size, multiply by the number of units: 1 unit ≈ 11.7 kWh, 4 units ≈ 46.8 kWh, 8 units ≈ 93.6 kWh, 16 units ≈ 187.2 kWh. Confirm the parallel limit and the inverter charge current before you finalise the string.
System voltage. This is a 51.2 V unit, so it matches the 48 V / 51.2 V class of hybrid and off-grid inverters and can sit on the same DC bus as other modules of the same voltage class.

OEM and ODM customization
Beyond the standard configuration, OSM builds to order: enclosure colour and branding, nameplate and label artwork, packaging, cable and connector sets, communication protocol selection and matched charger or inverter bundles. Send the target specification and the artwork, and the engineering team returns a drawing and a quotation.
Frequently asked questions
How long does this wall-mounted LiFePO4 home battery last?
The published cycle life is 6,000 cycles. At one full cycle per day that is well over ten years of service, and the usable life is normally limited by the depth of discharge and the operating temperature rather than by the cells themselves. Keep the pack inside its published temperature window and let the BMS manage the charge profile.
What chemistry does this wall-mounted LiFePO4 home battery use?
It uses lithium iron phosphate (LiFePO4 / LFP) cells with a nominal rating of 51.2 V / 230 Ah. LFP is chosen for this duty because it is thermally stable, holds a flat voltage curve for most of the discharge and tolerates daily deep cycling far better than lead-acid or NMC.
How much energy is that in practice?
The nameplate energy is about 11.7 kWh per pack. Usable energy is a little lower because most systems do not go to a full 100% depth of discharge — 90% is the usual planning figure, and that is what to use when you size the bank against daily consumption.
Which inverters and EMS platforms will it talk to?
Communication is CAN / RS485. That covers the mainstream hybrid, off-grid and C&I inverter protocols, so in most projects the battery pairs with the inverter without a protocol converter. Send us your inverter model and we will confirm compatibility before you order.
Do you supply samples and OEM branding?
Yes. OSM supplies single units and samples, and offers OEM/ODM on the enclosure, the label, the nameplate and the packaging. Send the artwork and the target specification and we will return a quotation with the lead time.
How is it shipped and what documents come with it?
Shipments go out as Class 9 dangerous goods with the UN38.3 test summary, the MSDS and the transport documents, packed for sea or air freight. Bulk orders can be consolidated so the container is loaded to suit your warehouse.
