Apollo B Series 5kWh All-in-One ESS - Apollo B series product image
The Apollo B Series 5kWh All-in-One ESS (model SCAP-B-51.2-100) offers a slim, horizontally oriented alternative to the stackable Apollo A, packaging a 51.2V 100Ah LiFePO4 battery and a 6KW hybrid inverter into a single 60 by 18.3 by 39 centimeter enclosure with 230V AC output. At 5120Wh, this compact 5kWh unit is ideal for apartments, small homes, and auxiliary buildings where floor space is limited but reliable solar backup is still required. The integrated MPPT controller accepts up to 9000W of PV across an 80V to 500V range with a 100A charge current, and the 100A discharge current covers essential circuits including lighting, refrigeration, and consumer electronics. The low-profile chassis can be wall-mounted or placed on a shelf, giving installers flexibility in tight utility rooms. CMJ Solar uses Grade A LiFePO4 cells rated for 2000 to 4000 cycles with a 5-year warranty, and every unit ships with CE, UN38.3, and MSDS documentation. For distributors serving urban and suburban markets where space is a constraint, the Apollo B 5kWh is a practical, easy-to-deploy residential storage solution. CMJ Solar offers factory-direct wholesale pricing and OEM customization from its Jiangmen, Guangdong facility. Request a quote at cmjsolar.com.

Product Overview

Is the SCAP-B-51.2-100 the Right Capacity for You?

Best suited for

The 5kWh Apollo B is a slim, wall-friendly alternative to the stackable A, using a 60 by 18.3 by 39 centimeter horizontal enclosure with a 6KW inverter. It suits apartments, small homes, and utility rooms where a tall module stack cannot fit but essential backup is required.

Typical loads this capacity handles

It starts and runs a fridge, lighting, internet, TV, and device charging on the 6KW inverter, with short microwave or coffee-maker sessions. Large air conditioning or simultaneous cooking loads are beyond it, matching the power profile of the A-series 5kWh model.

Estimated runtime

Backup example: about 4.5kWh usable. A 350W essential-load average lasts roughly 13 hours, covering an overnight outage for key circuits; a 500W load gives close to 9 hours.

Sizing advice

Pick the slim B 5kWh when wall space and a low profile decide the installation. It cannot be stacked in the same column, so capacity expansion means adding B modules side by side as separate units rather than extending one tower.

Frequently Asked Questions

What warranty does this product come with?

The Apollo B Series 5kWh 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 B Series 5kWh All-in-One ESS power my home during an outage?

The Apollo B Series 5kWh All-in-One ESS provides 5,120Wh of stored energy (approximately 4,608Wh 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 9.2 hours. At 1,000W, runtime is approximately 4.6 hours. Actual runtime depends on total connected load and usage patterns.

What appliances can the 6KW inverter handle?

The Apollo B Series 5kWh All-in-One ESS features a 6KW hybrid inverter with 230V AC output. At 6KW, 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 6KW rating.

Can this system operate off-grid and with solar panels?

Yes. The Apollo B Series 5kWh 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 B series uses a modular design that allows you to add battery modules over time. Each module provides 100Ah 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.
