POM OG SERIES OFF GRID SOLAR INVERTER STAND ALONE TRANSFORMER BASED

Range: 10 KW TO 250 KW (THREE PHASE)

POM OG Series Off-Grid solar inverter with an isolation transformer offers enhanced safety and reliability for solar power systems, particularly in areas with unstable grid conditions or where complete electrical isolation is desired. The POM OG Series provides galvanic isolation, protecting the system from voltage fluctuations and potential electrical hazards. It also helps to mitigate electrical noise and harmonics, improving overall power quality. The OG Series Off-Grid Solar Inverters range from 10 kW to 250 kW three-phase.

Detailed Specification

Description

MOST SUITABLE FOR REMOTE APPLICATIONS

An isolation transformer typically has a primary and secondary winding, with the primary winding connected to the DC-AC inverter circuit and the secondary winding connected to the load. Energy is transferred from the primary to the secondary through magnetic induction, without any direct electrical connection. This creates electrical isolation between the two circuits. This protects the load and reduces MTTF in POM OG Series Inverters.

VOLTAGE REGULATIONS

POM OFF-GRID Inverters can step up or step down the voltage, ensuring a stable and consistent output, even with fluctuations in the input voltage. Our inverters are capable of providing extended dependence on solar power during mornings and evenings when solar production is low.

PERFECT SOLUTION FOR HARSH ENVIRONMENTS

Our off-grid solar inverter, equipped with an isolation transformer, offers a robust and reliable solution for generating and distributing electricity from solar panels, particularly in challenging electrical environments. While it comes with some trade-offs, the enhanced safety, voltage regulation, and noise reduction capabilities make it a valuable asset for off-grid solar installations.

HIGH RELIABILITY AND INCREASED LIFESPAN

The POM OG Series Off-Grid Inverter’s ability to manage voltage fluctuations and surges enhances the overall reliability and lifespan of the off-grid solar system.

GALVANIC ISOLATION:

The isolation transformer creates a physical separation between the input (solar panels and battery) and output (loads) circuits, preventing current leakage and electrical hazards.

PROTECTION AGAINST SURGES AND SPIKES:

POM OFF-GRID floor-mounted inverters can handle voltage spikes and surges from the load side, protecting sensitive electronic equipment from failure and increasing the lifespan of the inverter.

NOISE AND HARMONIC REDUCTION:

Our inverters help to filter electrical noise and harmonics generated by the inverter, thus improving power quality for connected loads.

SAFE & RELIABLESAFETY ENHANCEMENT:

By providing electrical isolation, it minimises the risk of electric shock and ensures a safer operating environment.

SUITABLE FOR REMOTE AREAS:

Our inverters are especially suitable for remote locations where grid stability is a significant concern.
