Volt Polska ULTRA HYBRID PRO napelemes inverter 8K 3F 48/230V (8000W) + MPPT (200-650V) + Wi-Fi

ULTRA HYBRID PRO 8K 3F 48/230V (8000W) + MPPT (200-650V) + Wi-Fi is a modern hybrid inverter that combines both on-grid and off-grid operation.

Key Features:

• Combines the functions of an on-grid (grid-tied) and off-grid (island) inverter

• Easy parameter configuration via a touch LCD display

• Built-in smart meter and current transformers included with the inverter

• Compatible with the Ultra 5 energy storage system

• Short-circuit, overload, and temperature protection

• PC software via USB or external Wi-Fi remote control module included (monitoring and parameter control)

• Compatible with BMS systems

• Three-phase output with continuous power up to 8kW in off-grid mode (without grid power)

• Capability to connect a 3-phase generator with autostart option (built-in relay)

• 5 operating modes: Store Mode, Load First Mode, Battery First Mode, Grid First Mode, and Advanced Mode (manual scheduling of operating mode by hour)

• Parallel operation of up to three inverters possible

• Can work alongside other inverters connected to the building’s electrical system (charging the battery with energy surplus from another inverter)

What devices can the ULTRA HYBRID PRO 8K 3F power?

• Home electronics: TVs, set-top boxes, hi-fi systems, DVD players

• Home appliances: refrigerators, microwaves, blenders, toasters

• Office equipment: printers, fax machines, computers, monitors

• Power tools: drills, grinders, angle grinders

• Pumps and compressors

How does a hybrid inverter combine on-grid and off-grid functions?

On-grid mode:
When the photovoltaic installation is connected to the user’s electrical system through a bidirectional energy meter, the hybrid inverter operates like a standard on-grid inverter. It converts direct current (DC) generated by solar panels into alternating current (AC) used to power household electrical devices. Excess energy is sent through the inverter to the power grid.

Off-grid mode:
In off-grid mode, the hybrid inverter operates independently of the user's power grid. The energy harvested from solar panels is stored in batteries and then delivered to connected loads.

Battery Recommendations

When using ULTRA HYBRID inverters in photovoltaic systems (with cyclic battery charging), we recommend using batteries specifically designed for such use, e.g.:
GEL VPRO SOLAR, DEEP CYCLE VPRO SOLAR, or LiFePO4 lithium batteries.

Make sure to select the correct battery type and the appropriate charge current in the inverter settings. Incorrect charging parameters can lead to battery damage and void the warranty.

Using maintenance-free AGM batteries (e.g.: AGM, AGM OPTI, AGM VPRO series) in photovoltaic systems (with cyclic charging) may result in faster degradation and loss of capacity. These batteries are best suited for buffer operation, such as voltage backup and UPS systems.

As with any battery type, incorrect charging current settings can cause damage and void the warranty.
