Product
DK-PT series 3 phase off-grid inverter has the function of segmented charging and discharging,working without battery under special conditions.lithium battery activation function, which can be triggered by mains or solar.4 charging modes: solar only, mains priority, solar priority and solar&mains hybrid charging.2 output modes: mains bypass and inverter output, with UPS function.Adopting full-digital double closed loop control, combined with advanced SPWM.Advanced MPPT technology with efficiency of 99.9%.LCD screen and three LED lights can clearly indicate the status and data.Intelligent and variable-speed fan, efficiently dissipate heat and extend system life.Multiple safety protection functions: short circuit protection, over load protection,reverse polarity protection and so on.
Features
1. Supports lead-acid battery and li-ion battery connections.
2. With a dual activation function when the li-ion battery is dormant; either mains or photovoltaic power supply access can trigger the activation of the li-ion battery.
3. Support three-phase pure sine wave output.
4. Supports two PV inputs, with the function of simultaneously tracking the maximum power charging or carrying capacity of two MPPT.
5. Dual MPPT, efficiency up to 99.9%, single maximum current of 22A, perfectly adapted to high- power modules.
6. 4 charging modes are available: solar only, mains priority, solar priority, and mixed mains and PV charging. With time-slot charging and discharging setting function, it helps users to take advantage of peak and valley tariffs and save electricity costs.
7. With two output modes of utility bypass and inverter output, with uninterrupted power supply function.
8. LCD large screen dynamic flow diagram design, easy to understand the system data and operation status.
9. Support CAN, USB, Dry and RS485 communication.
