Ares 15kWh All-in-One ESS with 12KW Inverter
Model: SCAS-11KW-15KWh

Product Overview
Is the SCAS-11KW-15KWh the Right Capacity for You?
Best suited for
The Ares 15kWh with a 12KW inverter in a 78.2 by 57 by 40 centimeter cabinet is the high-spec Ares, aimed at large homes that run air conditioning, electric cooking, and multiple appliances together through long outages.
Typical loads this capacity handles
The 12KW output with 200A discharge drives heavy simultaneous loads and starts compressors with headroom, while the 15kWh block provides enough energy to use that power overnight rather than just for short bursts.
Estimated runtime
Backup example: about 13.5kWh usable. A 700W load lasts close to 19 hours and a 1500W load around 9 hours, so a large family runs real appliances through an extended outage with little load management.
Sizing advice
Choose the Ares 15kWh 12KW as the flagship floor-standing option for high-consumption homes. It competes with the Apollo A Pro 15kWh but in a one-piece cabinet rather than a stack, so the decision is mainly installation format rather than power or capacity.

Frequently Asked Questions
What warranty does this product come with?
The Ares 15kWh All-in-One ESS with 12KW Inverter comes with a 5-year warranty covering the LiFePO4 battery cells and integrated BMS. Our LiFePO4 cells are rated for 2,000-4,000 charge-discharge cycles, providing 5-10 years of reliable daily use under normal operating conditions. Spare parts and technical support are available throughout the warranty period.
What is the MOQ (Minimum Order Quantity)?
The MOQ is typically 20 units per model for standard products. Sample orders of 1 unit are welcome for testing and evaluation. For OEM/ODM custom packaging or private labeling, the MOQ is 500 units. Contact our sales team for specific pricing based on your order volume.
How long can the Ares 15kWh All-in-One ESS with 12KW Inverter power my home during an outage?
The Ares 15kWh All-in-One ESS with 12KW Inverter provides 15,360Wh of stored energy (approximately 13,824Wh usable at 90% depth of discharge). At an average essential-load draw of 500W (lights, router, refrigerator, and TV), it can sustain power for approximately 27.6 hours. At 1,000W, runtime is approximately 13.8 hours. Actual runtime depends on total connected load and usage patterns.
What appliances can the 12KW inverter handle?
The Ares 15kWh All-in-One ESS with 12KW Inverter features a 12KW hybrid inverter with 230V AC output. At 12KW, it can simultaneously run household appliances such as refrigerators (150-400W), LED lighting (10-50W), televisions (50-150W), computers (100-300W), and smaller air conditioning units. The inverter also supports surge power for motor startups. For high-power devices like electric ovens or heat pumps, verify the combined load does not exceed the continuous 12KW rating.
Can this system operate off-grid and with solar panels?
Yes. The Ares 15kWh All-in-One ESS with 12KW Inverter supports grid-tied, off-grid, and hybrid operation modes. It features an integrated MPPT solar charge controller with a PV input voltage range of 80V-500V, making it compatible with a wide range of monocrystalline and polycrystalline solar panel configurations. The system automatically switches to backup power during grid outages and can store excess solar energy for nighttime use.
What is included in the all-in-one design?
The Ares all-in-one ESS integrates the LiFePO4 battery bank, hybrid inverter, MPPT charge controller, and BMS into a single floor-standing cabinet. This pre-wired, factory-tested design significantly reduces installation time and complexity compared to separate component systems. It includes WIFI monitoring for remote system status tracking via mobile app.
