The VOLT Sinus Pro Ultra Plus 7000 24/230V (35000/7000W) solar energy inverter with 100A MPPT (60-500V) is a device that combines multiple functions: inverter, solar charger, and battery charger. The clear LCD screen allows easy and intuitive operation, using buttons for settings such as battery charging current, priority for solar/AC charging, and allowable input voltage depending on different applications.

• Operates as an off-grid inverter (standalone inverter)
• Adjustable input voltage range for devices and computers through settings on the LCD screen
• Adjustable battery charging current depending on application
• Adjustable AC/solar charging priority through settings on the LCD screen
• Cold start function
• Accurate output from pure sine wave
• 100A MPPT solar charge controller (60-500V)
• Compatibility with Ultra 5 energy storage system
• Capability to monitor device parameters via WiFi
• EQ function - optimization of battery performance and extension of battery life
• Supports multiple output priorities: UTL, SOL, SBU, SUB
• Protection against short circuit, overcharge, and temperature

The SINUS PRO ULTRA PLUS 7000 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
• Power tools such as drills, grinders, angle grinders
• Pumps, compressors

Battery activation function via deep discharge recovery: This feature is used to start (reactivate) a lithium battery that has been fully discharged and is unresponsive to commands. In some cases, the battery requires a short activation pulse before it can start charging normally - this is the option provided. The duration of this pulse can be set from 6 to 300 seconds. The default setting is 6 seconds, which is usually sufficient for most cases.

The EQ (Equalization) function aims to:

• Optimize battery performance by ensuring each cell operates within the optimal voltage range
• Extend battery life by preventing excessive wear of certain cells

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

For the optimal operation of the SINUS PRO ULTRA PLUS inverter in photovoltaic systems (cyclic battery charging), the use of appropriate batteries, such as GEL VPRO SOLAR, DEEP CYCLE VPRO SOLAR or LiFePO4 lithium batteries, is recommended.

Choosing the right type of battery and charging parameters is crucial to avoid battery damage and to validate the warranty. Maintenance-free AGM batteries (e.g., AGM, AGM OPTI, AGM VPRO series) can cause faster loss of performance/capacity.
