Outdoor IP65 Wall-Mounted LiFePO4 Battery (51.2V, 100Ah / 200Ah)
Product Overview
A 51.2V (48V class) wall-mounted LiFePO4 battery in an outdoor-oriented, IP65-class enclosure option, offered at 100Ah (≈5.12kWh) and 200Ah (≈10.24kWh). It is for installers who need to mount storage on a carport, façade, balcony or plant-room exterior instead of indoors.
Our existing wall-mounted pages (51.2V 100Ah, 51.2V 200Ah) cover the indoor format. This page covers the outdoor enclosure format, which distributors in Australia, the GCC and Africa re-order for sites where indoor space is not available. For import requirements in those markets, see the Saudi Arabia and UAE import checklist and the Africa import guide for Nigeria, Kenya, South Africa and Ghana. The IP rating of your build is confirmed per project.
Appearance, color and logo customizable per customer request.

Specifications
How to read Status — three classes: [Industry reference] = standard reference parameter common to this product class (not an LJY test result). [Optional configuration] = configurable per OEM/ODM project (BMS communication, parallel/series setup, heating, enclosure, logo). [Confirmed per project] = fixed only in the datasheet issued with your quotation. Arithmetic: energy = nominal voltage × Ah.
| Group | Parameter | Value | Status |
|---|---|---|---|
| Electrical | Voltage class | 51.2V (48V class), 16S | [Industry reference] |
| Electrical | Capacity / energy | 100Ah ≈ 5.12kWh · 200Ah ≈ 10.24kWh | [Industry reference] — arithmetic |
| Verification | Capacity confirmation method | Stated Ah and Wh are confirmed per project by the method agreed in the quotation (examples used in this industry: constant-current discharge to the BMS cut-off, BMS-reported capacity after a controlled cycle, or a factory capacity/test summary supplied with the shipment). This page does not publish a measured capacity figure. | [Confirmed per project] |

BMS, communication & protection
Outdoor units see wider temperature swings. BMS temperature thresholds and current limits should be set for the site climate.
BMS sizing guide
| Load / use case | Suggested BMS rating |
|---|---|
| Hot, sunny site (GCC, AU, Africa) | Shade + configured high-temperature limits |
| Cold site | Self-heating option (to be confirmed) |
| Multiple units | Parallel setup confirmed per project |
IP65 protects against dust and water jets; it does not make direct sun exposure safe. No verified high-temperature performance is claimed.
Size, handling & fitment
Mount on a load-bearing wall; check bracket and anchor rating for the unit weight (confirmed per design).
Install in shade with airflow clearance; avoid direct sun and enclosed hot spaces.
Use the specified cable glands and keep covers closed to maintain the enclosure rating.

The IP rating is an enclosure option and is confirmed per project and design.
How is MOQ set?
MOQ is confirmed per project stage (sample, pilot, production) and depends on cells, enclosure tooling and branding scope.
Which certificates apply?
Certificate scope is confirmed per model, order and target market. We do not claim certifications on this page.
Is it compatible with my inverter?
We do not publish a compatibility list. Communication protocol and settings are confirmed against your exact inverter or PCS model and firmware per project.
