Solar Inverter SINUS PRO ULTRA PLUS 3000

The SINUS PRO ULTRA PLUS 3000 solar inverter is a multifunctional device that combines an inverter, a solar charger, and a battery charger. A clear LCD display ensures easy and intuitive operation, allowing users to configure settings such as battery charging current, AC/solar charging priority, and permissible input voltage ranges depending on the application.

Key Features:

• Operates as an off-grid inverter

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

• Adjustable battery charging current via LCD settings

• Selectable AC/solar charging priority via LCD

• Deep battery discharge wake-up function

• Cold start capability

• Pure sine wave output

• Integrated 100A MPPT solar charge controller (30–500V)

• Compatible with Ultra 5 energy storage systems

• EQ function – enhances battery performance and extends battery life

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

• Protection against short-circuits, overloads, and overheating

Compatible Devices:

• 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 3000 Apart?

Deep Battery Discharge Wake-Up Function
This feature enables the device (e.g., a charger) to initiate the charging process even when the battery is deeply discharged—i.e., its voltage has dropped below the detection threshold of conventional chargers.

• Traditional chargers often do not start charging if the voltage falls below a certain level (e.g., 10V for a 12V battery) because the battery is not recognized.

• The wake-up function allows charging to begin from voltages as low as 2–3V, potentially preventing permanent battery damage.

• Especially useful with LiFePO4 battery types.

EQ (Equalization) Function
This feature balances voltage among battery cells to:

• Optimize performance – ensures all cells operate within their ideal voltage range

• Extend battery life – prevents premature wear of individual cells

• Intended for use with flooded lead-acid batteries.

How It Works in Off-Grid Mode:

In off-grid mode, the inverter operates independently of the public power grid. Solar energy collected by the panels is stored in batteries and then supplied to connected loads as needed.

Recommended Battery Types:

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

• GEL VPRO SOLAR

• DEEP CYCLE VPRO SOLAR

• Lithium LiFePO4

⚠️ Important:
Select the correct battery type and charging current settings. Incorrect configuration may damage the battery and void the warranty.
AGM batteries (e.g., AGM, AGM OPTI, AGM VPRO series) are not recommended for cyclic solar charging. These are better suited for standby (buffer) operation, such as UPS backup systems. Incorrect charging parameters can reduce performance and lifespan.
