The solar inverter VOLT Sinus Pro Ultra Plus 3000 is a device that combines multiple functions: inverter, solar charger, and battery charger. The clear LCD screen allows simple and intuitive operation, using buttons for settings such as battery charging current, solar/AC charger priority, and allowable input voltage depending on different applications.

• Operates as an off-grid inverter
• Adjustable input voltage range for devices and computers via LCD screen settings
• Adjustable battery charging current according to the application
• Adjustable AC/solar charging priority via LCD screen settings
• Battery activation function via deep discharge
• Cold start function
• Pure sine wave output
• 100A MPPT solar charge controller (30-500V)
• Compatible with the Ultra 5 energy storage system
• EQ function - battery performance optimization and lifespan extension
• Supports multiple output priorities: UTL, SOL, SBU, SUB
• Protection against short circuit, overcharge, and temperature

The SINUS PRO ULTRA PLUS 3000 can power:

• RTV devices such as televisions, receivers, hi-fi systems, DVDs
• Household appliances such as refrigerators, microwave ovens, blenders, toasters
• Office equipment such as printers, fax machines, computers, monitors
• Electric tools such as drills, angle grinders
• Pumps, compressors

The battery activation function via deep discharge allows the restart of a fully discharged lithium battery. In some cases, the battery requires a short activation pulse before it can begin normal charging. The duration of this pulse can be set from 6 to 300 seconds.

The EQ (Equalization) function optimizes battery performance by ensuring each cell operates within its optimal voltage range.

In off-grid mode, the solar inverter operates independently from the user's electrical grid. The energy obtained from solar panels is stored in batteries and then transferred to the connected load.
