Solar Inverter SINUS PRO ULTRA PLUS 7000

The SINUS PRO ULTRA PLUS 7000 is a multifunctional device that combines the functions of an inverter, a solar charger, and a battery charger. A clear LCD display enables simple and intuitive configuration using buttons for settings such as battery charging current, AC/solar charging priority, and acceptable input voltage depending on different use cases.

Key Features:

• Operates as an off-grid inverter

• Configurable input voltage range for household appliances and computers via the LCD display

• Adjustable battery charging current depending on the application, via the LCD display

• Selectable AC/solar charging priority via the LCD display

• Cold start capability

• Pure sine wave output

• Built-in 100A MPPT solar charge controller (60–500V)

• Compatible with the Ultra 5 energy storage system

• WiFi monitoring of device parameters

• EQ function – optimizes battery performance and extends lifespan

• Multiple output priority modes: UTL, SOL, SBU, SUB

• Short-circuit, overload, and temperature protection

Devices Powered by SINUS PRO ULTRA PLUS 7000:

• Consumer electronics: TVs, tuners, hi-fi systems, DVD players

• Household appliances: refrigerators, microwaves, blenders, toasters

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

• Power tools: drills, grinders, angle grinders

• Pumps and compressors

What Sets the SINUS PRO ULTRA PLUS 7000 Apart?

EQ (Equalization) Function
This process equalizes voltage between cells in lead-acid batteries to:

• Optimize battery performance – ensures that each cell operates within its optimal voltage range

• Extend battery life – prevents excessive wear of individual cells, reducing the risk of premature degradation

This function is intended for flooded lead-acid batteries.

How Does the Inverter Work in Off-Grid Mode?

In off-grid mode, the solar inverter operates independently of the public power grid. Energy generated by solar panels is stored in batteries and then delivered to connected loads.

Recommended Battery Types:

When using a SINUS PRO ULTRA PLUS series inverter in photovoltaic systems (for cyclic battery charging), it is recommended to use batteries specifically designed for this purpose, such as:

• GEL VPRO SOLAR

• DEEP CYCLE VPRO SOLAR

• Lithium LiFePO4

⚠️ Important:
Always select the correct battery type and charging current for the battery's capacity in the inverter settings. Incorrect charging parameters can damage the battery and void the warranty.

Using maintenance-free AGM batteries (e.g., AGM, AGM OPTI, AGM VPRO series) in photovoltaic systems with cyclic charging can lead to faster loss of efficiency/capacity. These batteries are best suited for buffer operation (voltage backup, emergency UPS systems).

As with all battery types, improper charging current settings can lead to damage and loss of warranty coverage.
