Apollo A Series 12KW 20kWh All-in-One ESS - Apollo A series product image
The Apollo A Series 12KW 20kWh All-in-One ESS (model SCAP-A-51.2-400P) brings together four stacked 51.2V 100Ah LiFePO4 modules totaling 20480Wh and a 12KW dual-MPPT hybrid inverter, producing one of the most powerful all-in-one residential storage platforms in the CMJ Solar lineup. Designed for large homes, multi-family dwellings, and small commercial sites, this 20kWh system supports dual PV inputs up to 2 by 7500W with a 160A charge current and an 80V to 500V MPPT range, feeding a 230V AC output with a 400A discharge current. That level of power means simultaneous operation of HVAC, electric vehicle chargers, and kitchen equipment without overload concerns. The modular column of four battery modules is pre-wired to the inverter head unit, cutting installation time on site. CMJ Solar backs the LiFePO4 cells with 2000 to 4000 cycle life and a 5-year warranty, and every unit ships with CE, UN38.3, and MSDS documentation. For distributors and EPC contractors serving high-consumption properties, the 12KW 20kWh Apollo A Pro is a premium offering that competes with top-tier brands at a factory-direct price point.

Product Overview

Is the SCAP-A-51.2-400P the Right Capacity for You?

Best suited for

The 20kWh Apollo A Pro with a 12KW inverter targets large homes and light commercial sites that demand both heavy simultaneous power and long backup, running climate control, kitchen loads, and electronics together through extended outages or off-grid periods.

Typical loads this capacity handles

Dual MPPT at two times 7500W and 160A charging refill four modules, while the 12KW output starts and runs compressors, ovens, and multiple appliances with comfortable headroom. It also suits small businesses whose daytime and evening loads overlap.

Estimated runtime

Backup example: about 18kWh usable. A 1000W load lasts roughly 18 hours and a 2000W load around 9 hours, supporting a large household or small shop for a full day of heavy use or longer under normal patterns.

Sizing advice

Choose the 400P for luxury homes and high-consumption families that want few compromises. Above this capacity the systems become property-specific installations; confirm floor load for the four-module stack and size the PV array to match 20kWh of storage.

Frequently Asked Questions

What warranty does this product come with?

The Apollo A Series 12KW 20kWh All-in-One ESS 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 Apollo A Series 12KW 20kWh All-in-One ESS power my home during an outage?

The Apollo A Series 12KW 20kWh All-in-One ESS provides 20,480Wh of stored energy (approximately 18,432Wh 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 36.9 hours. At 1,000W, runtime is approximately 18.4 hours. Actual runtime depends on total connected load and usage patterns.

What appliances can the 12KW inverter handle?

The Apollo A Series 12KW 20kWh All-in-One ESS 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 Apollo A Series 12KW 20kWh All-in-One ESS 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.

Can I expand the battery capacity later?

Yes. The Apollo A series uses a modular design that allows you to add battery modules over time. Each module provides 400Ah at 51.2V. Capacity can be scaled from 5kWh up to 30kWh (or higher depending on the configuration) by stacking additional modules without replacing the existing system. This modular approach protects your initial investment and allows capacity to grow with your energy needs.
