Power Supply Wall Mounted Battery Pack ESS 280Ah 300Ah

1. Can charge in CC/CP/ VP ways
2. Smart BMS offers many safeguards
3. A-level prismatic cell, deep cycle with a long lifespan

Homeowners and facility managers increasingly seek compact, high-performance storage. The Power Supply Wall Mounted Battery Pack ESS 280Ah 300Ah addresses this by combining high energy density with user-friendly mounting. Unlike floor-standing alternatives, wall-mounted designs utilize vertical space in garages, utility rooms, or outdoors (with proper IP-rated enclosures), minimizing footprint while supporting heavy loads.

These battery packs significantly enhance solar self-consumption rates, often exceeding 80-90% compared to 30-50% without storage. Excess daytime photovoltaic (PV) generation charges the battery, which then powers essential loads during peak evening hours or outages. Real-world data from installations show reductions in grid dependency by 50-70%, translating to substantial bill savings-potentially $500–$2,000 annually depending on local rates and usage. The LiFePO4 chemistry offers superior thermal stability, with operating temperatures from -20°C to 60°C, and cycle life exceeding 8,000 cycles at 80% depth of discharge (DoD), far outlasting lead-acid alternatives (typically 500–1,000 cycles). This longevity equates to over 15 years of reliable service under typical residential cycling, backed by warranties of 10+ years.

1. Raw material quality control: all raw materials will be fully inspected before production. Only those that pass the inspection can be used for the next production step.

2. During production, Each process is supervised by QC staff, who will conduct production inspections from time to time. Any problems found will be solved as soon as possible.

3. QC before shipment: all products will be subjected to aging tests, and each batch of goods needs to provide a full-process quality control report, and no defects are allowed.
