FAQS about On grid battery inverter Bulgaria

Who sells hypontech photovoltaic inverters in Bulgaria?

Hypontech photovoltaic inverters combine high quality and affordable price. NENCOM is the exclusive representative of Hypontech in Bulgaria. We sell on-grid and hybrid inverters wholesale and retail, we help with settings.

How does a hypontech on-grid inverter work?

The on-grid inverters Hypontech can be configured both to sell all the generated energy to the grid, and for self-consumption at the facility. In the second case, it is needed a smartmeter, and the settings allow to either limit the supply of excess energy to the grid, or allow it, depending on the agreement with the grid operator.

How much power does an inverter use?

The output power on each phase can independently vary from zero to 1/3 of the inverter’s rated power. In case of emergency shutdown of the grid, switching to battery operation takes less than 10 ms, providing uninterrupted power supply.

Does a hybrid inverter need a SmartMeter?

Output power in off-grid and emergency operation modes is not limited. When connecting the hybrid inverter to the grid, a smartmeter is not required, since the kit includes measuring current transformers (CT).

FAQS about Grid tie inverter specifications Aruba

What is a grid-tie inverter?

A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid.

How does a grid tie inverter work?

A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal computer that senses the current AC grid waveform, and outputs a voltage to correspond with the grid.

What is a grid-interactive inverter?

In the United States, grid-interactive power systems are specified in the National Electric Code (NEC), which also mandates requirements for grid-interactive inverters. Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid.

What is a transfer switch in a grid-tie inverter?

A transfer switch is also known as a transfer relay. Grid-tie inverters usually feature a built-in load transfer switch for backup emergency power applications. As long as utility power reaches the inverter’s AC input side, the transfer switch passes the AC grid power directly through the inverter to the load.
