FREQUENTLY ASKED QUESTIONS

ISUNA is Sinexcel’s line of advanced hybrid inverters and energy storage systems for residential and commercial use.

The ISUNA series is modular, flexible and fully customisable. It supports lithium, lead acid & many types and brands of battery. It uses Sic technology to achieve a 99% efficiency rating. The 3-phase models have two independent battery ports which doubles the capacity of the battery use, facilitating the use of both ports at the same time. The ISUNA integrates high-performance hybrid inverters with intelligent EMS and advanced lithium battery solutions.

Yes, hybrid Inverters can grow with you as your needs change or your budget allows. 

Yes, ISUNA systems can handle solar, battery, and grid inputs for seamless power management.

Yes, ISUNA can be an off -grid inverter and supports a standby generator if required.

Absolutely, the ISUNA systems support seamless transition between on-grid, off-grid, and backup modes.

Compatibility varies; Sinexcel recommends using approved battery models for optimal performance.

Yes, Isuna can, using the supplied power meter, Isuna can AC couple existing solar equipment.

Isuna has two independent battery inputs each with their own PCS/BMS, allowing additional batteries at a later time.

When the all round goes dark, Isuna can securely backup the site or critical loads.

With the supplied power meter Isuna can meet your site limitations.

This depends on the model, but ISUNA supports high DC input voltages and multiple MPPTs for flexibility.

Yes, it features a cloud-based EMS platform for real-time remote monitoring and control.

A hybrid inverter combines solar inverter functions with battery inverter functions, allowing for solar + storage configurations.

It manages both solar panels and battery storage, whereas a standard inverter only handles solar input.

Compatibility varies by model; always check the supported battery chemistries and communication protocols. One of the unique features of the Sinexcel ISUNA system is that it is compatible with batteries of different technologies (lead acid vs lithium) and from different brands.

Most modern hybrid inverters offer efficiencies between 95% and 98%. Due to the unique SiC technology implemented by Sinexcel, the ISUNA range is 99% efficient.

Yes, they can export excess solar energy to the grid, depending on local regulations.

It depends on your peak load, solar array size, and battery capacity—contact the team at Fuseco for more information.

Yes, especially in scenarios where backup power or time-of-use optimisation is needed.

An EMS is a system that monitors, controls, and optimises energy consumption in a facility or grid-connected environment.

By analysing consumption patterns and enabling automation or manual control to reduce energy waste.

Yes, EMS can integrate solar, wind, and battery storage systems for optimized energy flow. In fact, the Sinexcel ISUNA can integrate with batteries of different styles and brands.

Manufacturing, commercial buildings, utilities, data centers, and smart homes benefit significantly.

Yes, most EMS platforms offer real-time dashboards and alerts for proactive energy management.

Energy usage, voltage, current, power factor, frequency, and environmental conditions.

Absolutely! It identifies inefficiencies and peak demand times to lower energy bills.

Yes, it can interface with utility systems to shift or reduce load during peak hours.

Most modern EMS platforms are modular and scalable for future expansion.

By enabling energy savings, reducing carbon emissions, and supporting clean energy integration.
