Data sheet
VMIII TWIN Manual
 
Axpert VMIII TWIN 4kVA/4KW 24V, 5KW PV Inverter Charger has a double intelligent charging system which can be monitored from the LCD screen and this facilitates intelligent control. It is a pure sine wave and includes an MPPT charger that allows you to carry out a photovoltaic solar installation completely isolated from the electrical grid with or without a solar battery bank (lead acid, Gel, Lithium, etc.). Axpert VMIII TWIN enables a wide PV input voltage range from 60 VDC to 450 VDC. These features allow fewer panels to be required in the system. It also allows you to connect an alternating current source such as a generator or generator set (or the electrical grid itself) for advanced energy management, making it the best choice for your home, business or isolated house.

This inverter is designed without a transformer with state-of-the-art electronics, which allows reliable power conversion in a compact size and reduced weight.
 
Its high-resolution backlit LCD screen offers multiple user-configurable functions with very easy access, with it you can configure the battery charging current, the priority of the AC / Solar charger, the acceptable input voltage based on different applications and much more. 
 
The Axpert TWIN VMII Inverter Charger has a BMS communication port which allows direct communication with the lithium battery.

Axpert VMIII TWIN 4kVA/4KW 24V, PV 5KW Inverter Charger offers a series of interesting features and functions that place it above inverters from other brands:
- Removable LCD screen with remote use option (only the UTP cable needs to be extended) up to a maximum wiring distance of 20 meters.


- Built-in Bluetooth. You will be able to view and configure the inverter parameters from your Android smartphone, through the WatchPower App.

- Communications port for BMS. It integrates a communications port that supports the RS-485, CAN-BUS and RS-232 protocols to be able to communicate with lithium batteries that incorporate BMS in order to have energy readings provided by the battery on the inverter screen.

- Battery equalization. To extend the useful life of lead acid batteries, this function allows you to eliminate part of the sulfation that is generated on the plates of this type of deep cycle batteries, whether they are monobloc, open lead acid or OpzS stationary batteries.

- Possibility of operation without battery. Through this function, the inverter can be connected to the panels and the incoming electrical network and operate directly with the consumption without the need to have a connected battery bank. The consumptions connected to the inverter will be powered directly from the AC input or the photovoltaic panels without the need for a battery bank to be present.

- Easy repair of the ventilation system. Since most physical problems can appear due to failures in the ventilation system, the design of this inverter facilitates the possibility of replacing the fans without having to disassemble the unit for faster and easier maintenance.
- Has USB On-The-Go function to facilitate data download
- The VMIII TWIN series has a built-in WiFi interface ready for mobile monitoring. This technology allows wireless connection up to 6-7 meters in an open space.
