PHYB8K-3P IP65 3 phase dual mppt on off grid solar 8kw hybrid inverter is a high-efficiency solar inverter system that combines solar energy and grid-connected energy sources. It is capable of seamlessly switching between grid-tied and off-grid modes, ensuring a constant and reliable power supply. Solar energy systems, both on-grid and off-grid, have become popular due to their eco-friendly nature and cost-efficiency. One critical component in a solar energy system is the inverter, which plays a pivotal role in converting direct current (DC) from solar panels into alternating current (AC) for use in homes and businesses.

The IP65 rating refers to the protection offered by a device from dust and water, making it suitable for outdoor environments.

8KW Hybrid Inverter Features

IP65 Weatherproof Design

The IP65 rating certifies that these inverters are well-protected against dust, debris, and water, making them ideal for outdoor installations. They can withstand challenging weather conditions, including rain and extreme temperatures.

Hybrid Functionality

This solar power inverter is engineered to seamlessly switch between on-grid and off-grid modes, ensuring uninterrupted power supply. In on-grid mode, excess energy can be sold back to the grid, while in off-grid mode, it ensures self-sufficiency during power outages or in remote locations.

Three-Phase Compatibility

The inverter is designed to work seamlessly with three-phase electrical systems, providing efficient power conversion and distribution. This feature is particularly advantageous for businesses and large residential properties with high energy demands.

Dual MPPT Tracking

This inverter comes with dual Maximum Power Point Tracking (MPPT) technology, which optimizes energy production by tracking the maximum power point of each solar panel individually. This feature ensures that the inverter is always operating at peak efficiency, even when some panels are partially shaded or dirty.

Connect Lithium Battery

This hybrid power inverter can work with lithium battery storage systems, enabling the capture and utilization of excess energy. This feature ensures a reliable power supply even when the primary energy sources are unavailable.

Remote Monitoring

Stay connected to your energy system from anywhere using our mobile app or web portal. Monitor performance, receive alerts, and make adjustments remotely for ultimate convenience.

Energy Management Scenarios in All Day

Energy Management During Daytime

The Energy Management System (EMS) operates in its default self-consumption mode. The following scenarios illustrate the energy management process:

Scenario 1: Excess PV Power Generation Compared to Load Power Consumption

In this scenario, the PV power generation takes priority, with the Emergency Power Supply (EPS) loads receiving the first allocation, followed by regular loads, and finally, the battery.
When the battery reaches its full charge, any surplus power will be directed back to the grid. The amount of power fed back to the grid will not surpass the predefined feed-in limitation value established during the initial configuration.

Scenario 2: PV Power Generation Is Insufficient Compared to Load Power Consumption

In this situation, the battery will discharge to bridge the energy deficit.
If the combined power from the PV system and the battery remains inadequate to meet the load power requirements, the inverter will draw power from the mains (grid) to compensate for the shortfall.

Energy Management during Night

Battery Discharge: When there is available energy, the battery will discharge to supply power to the loads. It serves as the primary power source during this period.
Grid Power Supply: If the battery’s discharge power is insufficient to meet the load requirements, the grid will automatically provide power to the loads. This ensures a continuous and uninterrupted power supply, even in situations where the battery capacity is depleted or unable to support the load demand.

By combining the discharge capacity of the battery and the EPS power from the grid, the system ensures reliable and uninterrupted power supply during nighttime operations.

During the night, when the battery is depleted, it will enter standby mode. In this scenario, the grid will provide all the power needed for the loads.

Optimizing Energy Utilization Throughout the Day

In the morning
We experience minimal energy production while facing high energy demands. As the sun rises, our solar panels start generating power, although it may not be enough to cover our morning energy needs. To bridge this gap, our lithium battery bank kicks in, supplying stored energy from the previous day.

At noon
We reach the peak of energy production, but our energy demands are at their lowest. Throughout the day, our solar panels operate at maximum capacity. However, since there is no one at home, energy consumption remains significantly low. Consequently, most of the generated energy is directed towards storing it in the lithium battery bank.

During the night
Energy production drops, but our energy demands remain high. The highest daily energy consumption occurs in the evening, precisely when the solar panels generate minimal or no energy. To meet this evening energy demand, the lithium battery bank comes into play, providing the stored energy generated during the daytime.
