Solar DC Transformer for High-Voltage Pumping Systems

JNDCDC10K-V1

Product Introduction

The JNDCDC10K-V1 is a purpose-built DC-DC booster (solar DC transformer) that accepts high-voltage PV input and provides a regulated high-voltage DC output to solar pumping inverters. Designed specifically for high-voltage solar pumping applications, it lets you use longer PV strings and larger panels while maximizing PV harvest through dynamic MPPT. The unit improves system efficiency, reduces PV balance-of-system (BOS) cost, and simplifies array matching for 7.5 kW-class pump systems and similar deployments.

Product Features

  • Advanced dynamic MPPT control with MPPT efficiency >99%.

  • Boosts PV string voltage to match high-voltage pump inverter input (rated output 650 Vdc).

  • Robust outdoor design: IP65 protection, operating −25 °C to +60 °C, forced-air cooling.

  • Typical system cost savings 10–20% by enabling optimized PV string configuration and lower BOS cost.

Description

PV capture: Two MPPT inputs monitor PV strings; the booster accepts wide DC inputs.

MPPT optimization: Dynamic MPPT extracts maximum power from each string (MPPT efficiency >99%), even under partial shading or mixed string conditions.

Voltage transformation: The booster converts and conditions PV DC to a stable high-voltage DC output (rated 650 Vdc) that matches the inverter/motor drive input requirements.

Safe, reliable operation: Built-in protections and electrical isolation prevent reverse connection damage and protect downstream equipment; RS485 enables monitoring and integration into site SCADA.

System benefit: By allowing optimal string sizing and higher PV string voltages, the JNDCDC10K-V1 reduces required PV capacity and BOS cost — typical project savings are 10–20% while improving runtime and overall energy utilization.
