Inverter Single-phase solar charger isolated Axpert 5000VA 48V MKS III 5000-48V

Voltonic Axpert MKS III 5000-48V: The Inverter Highest Range Off-Grid Charger, High Voltage MPPT Regulator and Integrated Wi-Fi Mobile Connectivity

The configuration of autonomous solar installations that require high continuity in supply and excellent value for money finds its final ally on the third generation of the MKS series. The inverter Axpert MKS III 5000-48V unifies a single chassis a inverter pure wave, a powerful photovoltaic regulator and a battery charger from alternate font, consolidating as one of the most robust economic options for the most demanding residential and rural users.

High voltage hybrid structure, parallel scalability and Strings optimization

The main technical evolution of this Voltronic model versus previous generations lies in the adoption of an input power stage similar to that of the inverters industry. When expanding the operational range of the MPPT follower from 120 VDC to 430 VDC (Supporting an absolute limit of 450 VDC), the installer can group the in long series. This drastically reduces losses due to Joule effect on wiring and tap the cost of protective materials. If you are evaluating the deployment of the solar panels on tile roofs or metal roofs to feed this equipment, we suggest you review our selection of structures for aluminum with universal anchors.

Unlike other economic ranges of the sector, the MKS III stands out for its capacity for modular growth. Thanks to the parallelization card that includes serial, it is possible to interconnect up to a maximum of 9 inverters identical to multiply the total system power up to 45 kW or configure balanced three-phase networks. If you prefer compact self-installable solutions for instantaneous consumption without massive accumulation, you can explore the alternatives available in our catalog of balcony Kits of last generation.

80A smart charger, advanced management of batteries and perimeter safety

To keep the accumulators in an ideal health status, the Axpert MKS III incorporates an alternating current charger of 80 a, which can take energy from an auxiliary generator or conventional electrical network to rescue the system for prolonged periods of low radiation. Its dedicated communication port RS485 allows direct and native dialogue with the BMS of the main market lithium storage manufacturers. To coordinate the low voltage supply with this inverter charger, we invite you to examine the models available in our section of batteries stationary of deep cycle.

Operational security is backed by an intelligent monitoring system that prevents short-circuit failures, overvoltages and overloads at the 230 VAC consumption output. Likewise, the integration of Wi-Fi connectivity Native allows to monitor energy flows in real time from any smartphone with iOS or Android systems. If your project requires interconnected configurations to the public network with surplus injection, we advise you to analyze our range of inverters networking single-phase and three-phase.

Frequently Asked Questions (FAQ)

1. What main difference exists between this MKS III model and the Axpert King series? The most remarkable difference lies in the management of the solar field in continuous current. While the King model uses a low-voltage MPPT regulator limited to 125 VDC (which forces many combinations in parallel of ), the Axpert MKS III raises this range until 450 VDC. This allows you to connect a large number of solar modules into a single linear series, decreasing the thickness of the necessary wiring, simplifying the installation on the roof and significantly improving the overall efficiency of energy collection.
2. Is it mandatory to connect this inverter to an electric network to work? No, at all. The Axpert MKS III is a inverter charger designed specifically for isolated installations (off-grid). It can work fully autonomously using only the energy of the solar and 48V batteries. Its alternating current entry (AC) is optional and serves to connect a conventional generator or electrical network as a backup system to charge the batteries or feed the consumptions if the they do not give supply on very cloudy days.
3. How much total power can I achieve using the parallelization function? Thanks to the series integrated parallelization card, you can connect each other up to a maximum of 9 inverters in parallel. If bonds 9 units of the 5000W model, your single-phase system will reach a joint power of up to 45 kW. In addition, this electronic versatility allows you to configure the equipment to create a three-phase output network of 400V, ideal if you have engines, water pumps or industrial machinery in an isolated estate.
4. What type of 48V batteries are compatible with the RS485 port of this inverter? This inverter charger is compatible with traditional lead-acid batteries, gel and AGM, manually adjusting load voltages. However, its RS485 data port is designed specifically to communicate directly with the BMS system of the modern 48V lithium batteries. This intelligent connection allows the inverter know the exact state of charge and regular amperage in real time, drastically lengthen the useful life of lithium cells.
