Description
Developed by Deye, Deye 6.14kWh Battery – lithium iron phosphate (LiFePO4) battery series is a new energy storage solution that provides reliable power for a wide range of equipment and systems. It is especially suitable for high-power applications where installation space is limited, load-bearing capacity is restricted, and a long cycle life is required.
This Deye battery features an intelligent built-in Battery Management System (BMS) that monitors each cell’s voltage, current, and temperature for safe operation. The BMS also balances the cells during charging to extend the overall battery lifespan. Multiple units can be connected in parallel for greater capacity and longer power supply duration, making it a flexible component in solar and inverter installations.
These qualities make the RW-M6.1-B an ideal choice for solar suppliers and installers looking to support inverters in modern solar power systems.

Installation Guidelines & Safety Requirements
Installing the Deye 6.14kWh Battery (Model RW-M6.1-B) requires careful attention to environmental conditions, placement rules, and proper grounding to ensure optimal performance, safety, and long-term reliability.
Recommended Installation Environment
To protect your battery and maximise its lifespan, the battery module should be installed indoors, away from direct exposure to harsh environmental elements. The area should meet the following location conditions:
- Completely waterproof and free from moisture ingress.
- Flat and level wall surface for stable mounting.
- Free of flammable or explosive materials.
- Stable ambient temperature, ideally within the operating range of -20°C to 50°C.
- Optimal working range: 15°C to 35°C for battery longevity.
- Humidity-controlled environment with minimal dust and airborne contaminants.
- At least 2 metres away from any heat source.
- Minimum 0.5 metres clearance from the inverter’s air outlet.
- Avoid direct sunlight exposure or installation in enclosed, unventilated spaces.
- Do not cover or wrap the battery casing or cabinet.
- The area should be inaccessible to children or pets.
- Avoid locations with high salinity, humidity, or extreme temperature swings.
Caution: If ambient conditions exceed the supported operating temperature range, the battery pack will automatically shut down to protect internal components. Repeated exposure to harsh temperatures may significantly reduce the battery’s performance and lifecycle.
Mounting Distance & Positioning
When mounting the Deye RW-M6.1-B battery module:
- The distance from the battery pack to the wall should be between 0 to 40mm.
- If installing multiple battery packs, maintain at least 100cm spacing between units for adequate airflow and serviceability.
- Ensure proper ventilation in the installation area to avoid heat build-up—even though the battery has natural cooling and does not require forced ventilation, good airflow helps maintain system stability.
Grounding Requirements
For safe and compliant operation, the battery system must be properly grounded:
- Use the grounding harness provided (illustrated in Chapter 3 of the installation manual).
- Connect one end to the battery’s designated ground point.
- Connect the other end of the harness to your local grounding system, following applicable regional electrical standards and codes.
Proper grounding is essential for:
- Protection from electrical faults.
- Stabilising voltage during operation.
- Enhancing the overall safety of your hybrid solar storage system.

Ningbo Deye Inverter Technology Co., Ltd
Ningbo Deye Inverter Technology Co., Ltd is a leading solar inverter brand known for high-quality renewable energy products. Deye manufactures a range of solar inverters and battery storage solutions designed for efficiency and reliability.
Their inverters are widely used and often considered among the best solar inverters in Australia due to their robust performance and long warranties. As a globally recognized brand, Deye continues to innovate in the solar industry, delivering reliable power conversion and energy storage technologies.
The Deye 6.14kWh battery comes with a 10-year manufacturer’s warranty, reflecting its high quality and the company’s confidence in long-term performance.
Yes. The RW-M6.1-B is designed to be modular and scalable. You can connect up to 32 batteries in parallel (for a total of up to ~196 kWh of storage) at any time, which means you can start with one or a few units and add more Deye batteries later to increase capacity.
The Deye 6.14kWh Battery is optimized for use with Deye inverters and other compatible hybrid inverters. It communicates via standard CANbus/RS485, allowing integration with many inverter brands, but it works best with Deye’s own solar inverter models for full functionality.
The battery has a built-in intelligent BMS that manages and monitors each cell’s health (voltage, current, temperature) in real time. It keeps the battery balanced during charging and discharging, preventing issues and extending life. The system also supports remote monitoring through the connected inverter or a monitoring portal, and it allows firmware updates via a USB interface for easy maintenance.
Yes. When paired with a suitable hybrid inverter, the Deye 6.14kWh battery can provide backup power during a blackout. In the event of a grid outage, the inverter will draw power from the battery (and solar panels if available) to run essential loads, effectively creating a complete backup power system for your home or business.
