PV-GENSET Controller

PV-GENSET Controller Description

The PV-GENSET Controller is an advanced hybrid power management system designed to optimize the integration of solar PV (photovoltaic) power, diesel/gas generators (GENSET), and battery storage. It ensures efficient power distribution, reduces fuel consumption, and maximizes renewable energy utilization in off-grid or hybrid power systems.

Key Features:

  1. Automatic Power Source Selection – Seamlessly switches between PV, battery, and GENSET based on load demand and availability.

  2. Generator Start/Stop Control – Minimizes generator runtime by prioritizing solar and battery power, reducing fuel costs and emissions.

  3. Battery Management – Protects batteries from overcharge/deep discharge and optimizes charging from PV or GENSET.

  4. Load Prioritization – Manages critical and non-critical loads to ensure uninterrupted power supply.

  5. Remote Monitoring & Control – Some models support IoT connectivity for real-time monitoring and adjustments.

  6. MPPT Solar Charging – Maximizes PV power harvest with Maximum Power Point Tracking technology.

  7. Grid-Tie Compatibility – Some hybrid models allow grid interaction for excess solar export or backup power.

Applications:

  • Off-grid solar systems (homes, telecom towers, rural electrification)

  • Hybrid solar-diesel systems (industries, hospitals, commercial buildings)

  • Microgrids & backup power solutions

Product Description: PV-GENSET Controller (Hybrid Solar & Generator System Controller)

The PV-GENSET Controller is an intelligent energy management unit designed to seamlessly integrate and optimize power flow between solar photovoltaic (PV) arrays, backup generator sets (gensets), battery banks, and critical AC loads. It serves as the central “brain” for off-grid, backup, or hybrid power systems, ensuring reliable electricity, maximizing solar utilization, minimizing generator run-time, and protecting system components.

The controller’s primary function is automatic source prioritization and switching. It follows a user-defined logic to always select the most efficient and cost-effective power source available. Its typical operational hierarchy is:

  1. Solar PV (Primary): Uses available solar energy as the first priority to power loads and charge batteries.

  2. Battery Bank (Secondary): Draws from stored battery energy when solar is insufficient.

  3. Generator (Tertiary Backup): Automatically starts the backup generator only when battery voltage drops to a critical low-level setpoint (Low Voltage Disconnect – LVD). This prevents battery damage from deep discharge.

This genset auto-start/stop capability is its defining feature. By monitoring battery state of charge (SoC) or voltage, the controller sends a “start” signal to the generator when reserves are low, and a “stop” signal once batteries are sufficiently recharged. This dramatically reduces fuel consumption, maintenance costs, generator wear, and noise compared to systems with manual or timer-based generator operation.

Core Functions & Features:

  • Dual-Input Management: Handles DC input from solar charge controllers (PWM/MPPT) and AC input from the generator.

  • Advanced Charging Control: When the generator is running, the controller often integrates or communicates with a high-current battery charger to perform efficient bulk, absorption, and float charging.

  • Load Management & Shedding: More advanced models can manage non-critical loads (e.g., water heaters) by shedding them during generator operation to prioritize charging or reduce generator size requirements.

  • System Protection: Provides critical safeguards including over-voltage, under-voltage, overload, and short-circuit protection for batteries and connected equipment.

  • User Interface & Monitoring: Features an LCD display showing system status (source, battery voltage/SoC, power flow) and allows for parameter configuration (start/stop voltage levels, charging currents).

  • Grid Compatibility (in some models): In hybrid on/off-grid systems, it can also manage utility grid interaction as a fourth power source.

Typical Applications:

  • Off-Grid Homes & Cabins: Where solar is the main source, backed by a generator for prolonged cloudy periods.

  • Remote Telecom Sites: Ensuring 24/7 power availability with minimal generator intervention.

  • Backup Power Systems: For critical infrastructure where solar extends backup runtime and reduces generator dependence.

  • Industrial & Agricultural Sites: Powering equipment in areas without a stable grid connection.

By intelligently orchestrating solar, battery, and generator resources, the PV-GENSET Controller delivers the ultimate balance of reliability, efficiency, and operational economy for demanding standalone and hybrid power systems.
