Photovoltaic and wind turbine inverters

Product enquiry 

We are a Polish manufacturer of on-grid and off-grid inverters for photovoltaic installations, wind turbines and water generators. These are Polish products we started working on under the grant III-070 P - 081/2010 "A family of single-phase (2.0, 3.0 and 5.5 kW) high-efficiency and transformerless DC / AC converter systems for solar farms” and then we continued to develop the product in-house.

With each device you get access to the portal, which enables monitoring of data from the installation.

Before placing an order, it is necessary to read the technical documentation the documentation placed at the bottom of the page. The TWERD ENERGO-PLUS company produces inverters with specific parameters, therefore the buyer is obliged to familiarize himself with them before purchasing the inverter. Without access to data on which wind turbine the inquiry concerns, we are unable to determine what kind of electricity production will take place, or whether it will be produced at all. TWERD ENERGO-PLUS does not guarantee satisfactory results for wind turbines not tested with our inverter.

Our offer:

1. Solar inverters

  • single-phase on-grid PS100-PV type, power 3.0 kW
  • single-phase on-grid or off-grid with a built-in battery charger PS100-PV+BC type, power 3.0 kW
  • three-phase on-grid type PS300-PV, powers: 3.0 kW, 5.0 kW, 8.0 kW, 10.0 kW

2. Wind turbine generator inverters

  • single-phase on-grid type PS100-WT, power 3.0 kW
  • three-phase on-grid type PS300-WT, powers: 3.0, 5.0, 8.0, 10.0 kW

3. Solar-wind inverters designed for simultaneous work with solar panels and a wind turbine.

  • three-phase on-grid type PS300-H, powers: 5.0 kW, 8.0 kW, 10.0 kW

It is possible to purchase an external PS Energy Guard measuring device for the inverters, which monitors the energy balance in renewable energy installations and energy storage system. The PS Energy Guard module measures the active, reactive and apparent power of a single-phase or three-phase network and sends the current values ​​to the PS100 or PS300 systems.
The PS Energy Guard module is not an electricity consumption meter and its readings cannot be used to settle electricity consumption.

Individual designs other than the standard products we offer are possible after testing the turbine together with our inverter in a specialized research unit at the customer's expense.

Despite every effort, the inverter manufacturer does not guarantee the effectiveness of the protection devices protecting the turbine against reaching unintended rotational speed, i.e., among others: correct operation of the relays switching on the braking resistors and controlling the operation of the tail.
For this reason, it is necessary to use an additional system, independent of the inverter, to protect the turbine against achieving unintended rotational speed or other factors that may cause damage to the turbine itself and other resulting consequences.
The manufacturer's liability towards the buyer is limited to the value of the product determined according to the manufacturer's suggested retail price on the date of purchase and does not cover damages resulting from its damage or faulty operation.
