The solar inverter VOLT Sinus Pro Ultra Plus 12000 48/230V (6200/12000W) features a 120A MPPT (60-500V) and combines multiple functions: inverter, solar charger, and battery charger. The clear LCD screen allows simple and intuitive operation, using buttons for settings such as current battery charging, solar/AC charger priority, and allowable input voltage depending on different applications.

• Operates as an off-grid (island) inverter
• Adjustable input voltage range for devices and computers via LCD screen settings
• Adjustable current battery charging according to the application
• Adjustable AC/solar charging priority through LCD screen settings
• Cold start function
• Pure sine wave output
• 120A MPPT solar charge controller (60-500V)
• Compatible with the Ultra 5 energy storage system
• Ability to monitor device parameters via WiFi
• EQ function - optimizes battery performance and extends its lifespan
• Supports multiple output priorities: UTL, SOL, SBU, SUB
• Protection against short circuit, overcharge, and heat

The SINUS PRO ULTRA PLUS 12000 solar inverter powers devices such as:

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

The battery activation function through deep discharge allows starting (reactivating) a lithium battery that is fully discharged and unresponsive to commands. In some cases, the battery needs a short activation pulse before it can begin charging normally. This option allows setting the duration of this pulse between 6 and 300 seconds.

The EQ (Equalization) function optimizes battery performance by ensuring each cell operates within its optimal voltage range. This function is used for lead-acid batteries with liquid electrolyte.

In off-grid mode, the solar inverter operates independently from the user’s electrical grid. The energy obtained from the solar panels is stored in batteries and then transferred to the connected load. It is recommended to use suitable batteries for photovoltaic installations, such as GEL VPRO SOLAR, DEEP CYCLE VPRO SOLAR, or LiFePO4 lithium batteries.
