Hybrid-Inverter Outdoor Air-Cooled BESS

Overview

Unlike a standard inverter (one function), it lets you use multiple energy sources (solar, grid, generator) and switch between them automatically. For example, it uses solar first (free energy), then grid (low rates), then generator (backup)—maximizing savings. A hybrid inverter combines three functions: 

1) Solar inverter (converts DC solar energy to AC); 

2) Battery inverter (converts DC battery energy to AC); 

3) Grid-tie inverter (feeds excess energy to the grid). 

Product Advantages

Hybrid Inverter Adds Multi-Source Flexibility

The 50kW side-mounted hybrid inverter is the system’s standout feature. It connects to three energy sources:

1) Solar panels (charges battery with renewable energy); 

2) Grid (charges during off-peak hours); 

3) Generator (backs up during cloudy/off-grid days). It also powers both AC loads (e.g., lights, appliances) and DC loads (e.g., solar charge controllers, DC pumps)—no separate converters needed.

Compact Design Fits Small Outdoor Spaces

At W800*H2300*D1300mm, the system is far smaller than utility-scale container BESS units. This makes it perfect for locations with limited space: the side of a gas station, a remote cabin’s yard, or a small farm. It can be installed in areas where larger systems would be impractical—without sacrificing capacity (110.6kWh is enough for 1-2 days of off-grid use).

Outdoor Durability with IP54 Rating

The IP54 rating protects the entire system (battery and inverter) from dust and splashing water. This means no additional enclosure is needed—install it directly outdoors, even in rainy or dusty areas. The inverter’s side-mounted design also prevents water pooling on top of the unit, further reducing corrosion risk.

All-Climate Operation

Whether you’re in a region with -20℃ winters (e.g., northern Canada) or 55℃ summers (e.g., Arizona), the system performs consistently. It discharges efficiently in cold weather (critical for winter backup) and charges safely in heat (up to 45℃). This versatility eliminates the need for climate-specific modifications.

Applications

Small Commercial Cost Reduction

For small businesses (convenience stores, cafes, small offices), the system cuts energy costs by storing off-peak grid power (low rates) and using it during peak hours (high rates). The 50kW inverter also integrates small solar panels (10-20kW) to further reduce grid reliance—slashing monthly bills by 15-25%.

Off-Grid Residential/Rural Power

In remote areas without grid access (mountain cabins, rural farms), the system acts as a primary power source. It charges via solar panels (daytime) or a generator (cloudy days) and powers all loads: lighting, refrigeration, irrigation pumps, and small appliances. The 110.6kWh capacity provides 1-2 days of power without recharging.

Temporary Event Power

For outdoor events (music festivals, construction sites, emergency camps), the system offers quick, portable power. Its compact size lets it be deployed in hours, and the 50kW inverter powers event equipment (stage lights, tools, communication radios). The 110.6kWh capacity runs equipment for 8+ hours at half load (25kW).

Small Critical Facility Backup

Small healthcare clinics, community centers, and cell towers need backup power. The system automatically switches to backup mode during outages, powering critical equipment (medical exam lights, vaccine fridges, communication gear) for 3-5 hours—preventing disruptions to essential services.

FAQ

Is the side-mounted inverter easy to maintain?

Yes. The inverter is pre-installed at the factory and accessible via a hinged panel on the side of the unit. Maintenance tasks (e.g., checking connections, updating firmware) can be done without moving the entire system. The inverter also has built-in diagnostics: it sends alerts via app/email if issues arise (e.g., low efficiency, connection problems).

Can it power both AC and DC loads?

Absolutely. The 50kW hybrid inverter converts DC battery/solar energy to AC for standard loads (e.g., TVs, tools, air conditioners). The system also has a dedicated DC output port (connected to the battery bank) for DC loads (e.g., DC fans, solar charge controllers, DC water pumps). This eliminates the need for a separate DC-DC converter, simplifying wiring.

What's the battery's expected lifespan?

The LiFePO4 battery cells have a cycle life of 3000-4000 cycles (at 25℃, 0.5C/0.5C, 80% EOL). For a typical user who discharges the battery once per day (e.g., peak shaving), this translates to 8-10 years of use. LiFePO4 batteries also have no “memory effect” (partial charges don’t reduce lifespan), so you can charge them as needed without harm.
