Description

Solvic DC Combiner box for 48V / 51.2V Solar Battery
This product is used with low-voltage lithium iron phosphate battery pack. It is compact, easy and quick to install,and has over-current and over-voltage protection measures, making the system operation more efficient and safer.
At the same time, it effectively solves the problem of inconsistent battery pack capacity when multiple low-voltage battery packs are running in parallel. It is widely used in small-scale industrial and commercial and household energy storage.
Why Choose DC Combiner Box?
🔗High Scalability and Flexibility
Multiple Access: Up to 8 low voltage battery inputs can be accessed and managed at the same time to meet different capacity requirements of the energy storage system configuration.
Modular Expansion: Users can start with a small number of batteries and gradually expand the capacity of the system according to the initial investment and later needs, protecting the initial investment.
🛡️Superior Safety Protection
Anti-reverse Connection Design: It is equipped with physical or electrical anti-reverse connection function to avoid equipment damage or safety accidents caused by misuse.
High-quality Materials: Flame-retardant and durable housing materials and high-quality conductive parts are used to ensure long-term stable operation.
🌞Efficient Energy Harvesting
Low-loss Design: Optimise the internal structure and busbar design, and choose low-resistance materials to minimise the loss of energy in the convergence process and improve the overall efficiency of the system.
Stable Output: Ensure that the parallel-connected batteries can provide power to the load or inverter in a stable and reliable manner.
🔧Easy Installation and Maintenance
Clear Layout: The internal terminals are clearly laid out and labelled, making it easy for users to quickly and accurately complete the connection of battery cables.
Compact Structure & Easy Installation: Compact structure design supports wall-mounting or other standard installation methods, saving installation space and simplifying the deployment process.

FAQs
-
Q
What is a battery combiner box?
AA battery combiner box is an enclosure that consolidates multiple battery connections into fewer outputs. It is commonly used in solar storage systems where multiple batteries are connected in parallel to increase total capacity.
-
Q
Is this the same as a PV combiner box?
ANot exactly. A standard PV combiner box combines solar panel strings before sending DC power to the inverter. This product is specifically a battery-side combiner box designed for parallel battery wiring, not solar panel input.
-
Q
Can I use this with LiFePO₄ batteries?
AYes. This combiner box is suitable for LiFePO₄, lithium-ion, and lead-acid battery banks when used with compatible system components, correct cable sizing, and proper installation.
