Detachable LCD Display

The ORVALDI MVIII5K is equipped with a detachable LCD display that can be connected via an RJ45 cable, allowing users to monitor system performance from a more convenient location. This flexible setup enhances user comfort, especially when the inverter is installed in hard-to-reach or enclosed spaces. By relocating the display, users gain easier access to system data and controls without needing to approach the device directly.

Connection types
The ORVALDI MVIII5K also supports wireless communication via Bluetooth Low Energy (LE) and Wi-Fi, enabling users to monitor and manage the system remotely through a mobile app. This wireless access adds significant convenience, allowing real-time performance tracking and configuration without needing to be physically near the inverter. It's an ideal solution for users who want flexibility and easy integration into smart energy systems.
Remote access
ORVALDI MVIII5K inverter is equipped with Wi-Fi connectivity, allowing users to monitor and manage the system conveniently. Once connected to a Wi-Fi network, the inverter can be accessed locally via the home network or remotely from anywhere in the world using the compatible mobile app. This ensures real-time performance tracking and greater control, no matter where you are.

Different invertor configutaions
The ORVALDI MVIII5K inverter can operate in both battery-supported and battery-less configurations, offering flexibility for different installation needs.
-
With Battery: The system stores excess solar energy in the connected battery, which can be used later when solar power is insufficient (e.g., during the night or cloudy conditions). It also supports charging the battery from the utility grid when needed, ensuring uninterrupted power for your home appliances.
-
Without Battery: The inverter supplies energy directly from solar panels to home appliances. When solar production is low, it automatically switches to utility power, maintaining a seamless power supply without requiring energy storage.
Charger and Output Source Priorities
Choosing the right charging and output source priority in ORVALDI inverters allows users to optimize energy efficiency, cost savings, and reliability based on their specific needs. Each mode offers distinct advantages, catering to different preferences and system setups.
Solar First Priority (SBU)
- How it works: This mode prioritizes charging the batteries from solar panels. The grid is only used when solar energy is insufficient, ensuring that renewable energy is maximized.
- Advantages: Ideal for maximizing savings and sustainability, it reduces reliance on traditional energy sources and lowers electricity bills. It's an excellent way to minimize your carbon footprint.
- Who is it for?: Perfect for individuals and businesses with well-established solar systems who want to fully harness solar power and prioritize renewable energy.
Utility First Priority (USB)
- How it works: In this mode, the grid is the primary source for charging the batteries. Solar power is secondary, ensuring that your system remains reliable, even in less favorable weather.
- Advantages: Ensures continuous power by prioritizing grid electricity when solar energy is limited. This guarantees stable power supply and uninterrupted operation.
- Who is it for?: Best for users in areas with less access to solar energy or for those who prioritize reliability and need stable, 24/7 power.
Solar and Utility (SUB)
- How it works: This balanced approach charges the batteries using both solar energy and the grid simultaneously. This dual-source charging ensures faster battery recharge and energy efficiency.
- Advantages: The combination of solar and grid energy provides the flexibility to optimize charging speed and energy use, enhancing both reliability and cost-effectiveness.
- Who is it for?: Suitable for those who seek the fastest battery charging times while still benefiting from renewable energy savings.
Only Solar
- How it works: This mode relies solely on solar energy for charging the batteries, with minimal grid involvement.
- Advantages: By fully utilizing solar energy, users can achieve energy autonomy and significantly reduce their dependency on the grid, leading to lower energy costs.
- Who is it for?: Ideal for users who aim for complete energy independence and are committed to reducing grid usage as much as possible.
Battery type
Battery Type: Tailored to Your Needs
- AGM (Default): This battery type is ideal for users seeking a maintenance-free, robust solution with a long lifespan. AGM batteries offer high efficiency at low maintenance costs.
- FLD (Flooded Lead-Acid): FLD batteries are traditional lead-acid batteries with liquid electrolyte. They are characterized by lower upfront costs and are widely used in various applications. This is a great option for those who need a proven and cost-effective solution but are willing to perform regular maintenance, such as topping up with distilled water.
- User-Defined: For more advanced users who want full control over their system, the user-defined option allows precise adjustment of charging voltage and DC cutoff thresholds. This option is ideal for custom settings for specialized battery types, such as lithium-ion.
