Understanding BMS and its Integration with Solar Inverters

As an experienced engineer in the lithium battery field, I have gained valuable knowledge and expertise in the industry. Today, I’m going to share my opinion on the battery management system (BMS) and how it communicates with the solar PV, focusing on Redway’s perspective.

The role of BMS:

BMS (Battery Management System) plays a vital role in monitoring and managing the performance of Li-ion batteries. It keeps the battery operating within safe parameters by preventing overcharging, undervoltage and high temperature. If any unsafe situation occurs or BMS fails, it will automatically shut down the battery to protect the battery. Redway prioritizes the incorporation of properly sized BMSs into our lithium battery solutions to ensure optimal performance and safety.

Communication between BMS and solar inverter:

Lithium-ion batteries are the preferred choice for solar photovoltaics due to their fast charging capabilities and their ability to consume direct current from solar photovoltaics. To increase power and eliminate errors, BMS systems are integrated into these batteries. But how the BMS communicates with the solar PV This is achieved by using the solar PV protocol and Li-ion battery protocol. At Redway, our solar photovoltaics are equipped with an innovative BMS system and lithium battery protocol for seamless communication and coordination.

Advantages of Redway 48V lithium-ion battery:

Redway’s Lithium-Ion batteries offer features with protective features, of which our 48V Lithium-Ion batteries are particularly notable. Let’s explore the benefits it brings:

1. Long cycle life:

Our lithium-ion batteries have a charge cycle of over 3,000, ensuring they can last for over 5 years with proper care. This longevity provides excellent value to our customers.

2. High density, portable and light:

Our 48V Li-Ion battery weighs around 44kg and is compact in size, which is very much in need of explanation. This sets the ideal solution for portable solar PV generators or any application requiring mobility.

3. Performance over a wide temperature range:

Redway’s lithium batteries provide excellent performance in a temperature range of -20°C to 55°C. While it is recommended that the battery be stored in a cooler environment to determine optimal performance, it will still perform reliably in a wide range of conditions.

4. High safety standards:

Our lithium-ion batteries feature a smart BMS that ensures protection against over-charging, over-draining, over-current, short-circuit and over-heating conditions. Safety is Redway’s wastewater mission.

5. Robustness:

Our 48V Lithium-Ion batteries utilize state-of-the-art materials and technology designed to withstand extreme temperatures and ensure safe operation in any environment. Its solid exterior and durable construction guarantee longevity and reliability.

6. Environmental protection:
