SRNE MPPT 30A DC-DC Solar Charge Controller MD1230N05

The SRNE MPPT 30A DC-DC Solar Charge Controller (model MD1230N05) is a high-efficiency MPPT regulator designed for off-grid solar systems. It automatically adapts to 12V/24V/36V/48V battery banks and supports a maximum PV input voltage of 150V. With a maximum charge current of 30A and conversion efficiency up to 98%, it ensures optimal energy harvesting from solar panels.

Advantages

Advanced MPPT technology with tracking efficiency >99.5% maximizes solar power output. Multi-stage charging algorithm (Bulk, Absorption, Float, Equalization) extends battery life. Common negative grounding design enhances safety and compatibility with various battery types including lead-acid (Sealed, Gel, Flooded) and lithium (LiFePO4, Li-ion, User-defined). LCD display provides real-time system monitoring. RS485 communication interface allows remote monitoring and configuration.
