Hybrid inverter Sinexcel Isuna 18kW, high-voltage: 180-800V, IP65, 2x battery inputs, meter and Wi-Fi module included ISUNA 18000T

Hybrid Inverter with Two Independent Battery Ports and Built-in Meter

This device operates as a hybrid solar inverter, combining energy generation from photovoltaics, battery storage, and grid/off-grid power supply—all in a single enclosure. Designed for use in both single-family homes and commercial facilities, it delivers stability and flexibility in energy management.

It operates with battery voltage ranging from 180–800 V, enabling compatibility with various battery types—lithium-ion, lead-acid, and even sodium-ion (optionally). Two independent battery ports allow mixing old and new batteries within the same system without risk of instability—ideal for users gradually expanding their energy storage.

The built-in multifunction meter tracks consumption, production, and energy flow between the grid, PV, and battery—eliminating the need for additional monitoring devices. The WiFi module and mobile app enable remote monitoring and control via smartphone, providing real-time data and historical usage analytics.

The UPS mode features a switching delay of less than 10 ms, ensuring uninterrupted power supply during grid outages—critical for sensitive equipment. The inverter supports 100% three-phase asymmetry, allowing balanced load distribution across phases—essential for uneven usage scenarios (e.g., motors on a single phase).

Outdoor installation is possible thanks to IP65 protection and passive air cooling—no fan or additional insulation required. The enclosure is resistant to dust, moisture, and extreme temperatures from -25°C to +60°C. Noise level is low—below 45 dB(A)—ensuring silent operation in residential environments.

Built-in protections include:

• Surge protection (Level II)
• Reverse polarity protection (PV and battery)
• Lightning protection

Up to 6 units can be connected in parallel, enabling system scaling up to 108 kW without replacing the main inverter. This supports integration with VPP (Virtual Power Plant) systems, opening access to demand-side energy management programs.

Efficiency exceeds 98.2%, with a maximum PV input power of 27 kWp—sufficient to meet most residential needs for a standard 10–12 kWp installation.
