Voltronic Axpert VM III TRI 4.5K features

4500VA/4500W with a 9000VA surge

Rated 4500VA/4500W and regulated to 230VAC ± 5% at 50Hz or 60Hz, with 9000VA of surge headroom for motor starts.

6500W of PV on a 120A MPPT charger

The MPPT tracker works from 60 - 450 VDC to a 500 VDC open circuit, accepting 40A and 6500W of array at up to 120A of solar charging.

24 VDC bank, 60A default charge current

Charges a 24 VDC bank at a 60A default current and up to 120A from AC, floating at 27Vdc, starting from 23.0Vdc and stopping at 33 VDC.

10 ms transfer across 90-280 VAC

Accepts a sinusoidal 230Vac utility or generator feed from 90-280 VAC to 300Vac, transferring in 10 ms at over 95% line-mode efficiency.

Disconnects at 280Vac±7V and 65±1Hz

Drops the line at 280Vac±7V or 65±1Hz and returns at 270Vac±7V or 63±1Hz, with 40±1Hz and 42±1Hz on the low side and a circuit breaker on short circuits.

11.8 kg in a 336 x 435.5 x 131 mm case

An 11.8 kg chassis measuring 336 x 435.5 x 131 mm, rated -10°C to 50°C and 5% to 95% relative humidity, non-condensing.

About the Voltronic Axpert VM III TRI 4.5K

The Voltronic Power Axpert VM III TRI 4.5K is a 4500VA/4500W inverter-charger built on a 24 VDC battery bank. It holds 9000VA surges, takes up to 6500W of PV through a 120A MPPT solar charger tracking from 60 - 450 VDC, and weighs 11.8 kg. Solar input is capped at 40A and 500 VDC open circuit, read to 2V PV voltage accuracy. On the AC side it accepts a sinusoidal 230Vac feed from utility or generator across 90-280 VAC, narrowing to 170-280 VAC in the personal-computer setting, up to a 300Vac ceiling, and transfers in 10 ms in that setting at better than 95% line-mode efficiency. Output is regulated to 230VAC ± 5% at 50Hz or 60Hz auto detection. Charging runs at a 60A default current and up to 120A, floats at 27Vdc, starts from 23.0Vdc and stops at 33 VDC. A circuit breaker covers short circuits, while USB, RS232, RS485, WiFi and dry-contact handle monitoring. The 336 x 435.5 x 131 mm chassis runs from -10°C to 50°C. It is sold with a 2-Year Manufacturer Warranty. We are an authorised Voltronic Power distributor.
