High-Voltage Solar Charger

JNCHF Series

Product Introduction

JNTech High-Voltage Solar Charger is a purpose-built DC charging unit to deliver safe, efficient and scalable PV charging for solar pumping and high-voltage storage applications. Designed for harsh field conditions, the charger combines a wide Vmp input window, higher conversion efficiency and multiple isolation protections. So installers can maximize PV utilization while keeping system and personnel safety top of mind. Compact, fan-cooled and available in common battery voltages (12V / 24V / 48V variants and multiple current ratings), the unit expands the range and economics of high-head solar pumping and other high-voltage PV projects.

Product Features

Wide PV input range to match high-voltage PV arrays and maximize solar harvest.
Multiple electrical isolation layers for user and system safety.
Anti-reverse connection protection for both PV input and battery output.
Compatible with JNTech high-MPPT range solar pump inverters and high-voltage pumping systems.

Description

Role: The High-Voltage Solar Charger is installed between the PV array and the battery/inverter subsystem.

It accepts DC from the PV array, performs optimized, demand-oriented charging, and outputs regulated DC to the battery bank.

It accepts a wide PV voltage range. Power is converted with high efficiency, minimizing losses and heat.

Built-in MPPT-style control (matching JNTech wide MPPT inverters) ensures more energy harvested.

Typical applications: high-head solar water pumping, high-voltage battery charging in microgrids, hybrid solar + battery installations where long PV strings or high PV voltage are used to reduce cable loss and BOS cost.

Safety & isolation: Multiple layers of electrical isolation prevent high-voltage leakage and ensure EMC compatibility in variable-frequency environments; the unit also includes anti-reverse protection on PV and battery terminals.

Protection & reliability: Comprehensive fault protections (over-voltage, over-current, short circuit, radiator over-temperature, etc.) plus forced cooling enable continuous, long-term operation even under heavy duty and high-head pump scenarios.

System synergy: When combined with JNTech solar pumping inverters and multi-stage pump units, the charger helps optimize energy flows, reduce reactive power and lower lifetime costs—making it ideal for high-head irrigation and remote water-supply projects.
