Apollo B Series 5kWh All-in-One ESS
Model: SCAP-B-51.2-100

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.
