PV questions – Imeon Energy

Which solar panels can be used with Imeon?

Because Imeon inverter is compatible with mono and poly crystalline solar panels. Do not connect any solar panels that may introduce leakage current to the inverter (such as non-grounded PV modules).

NOTE : The PV DC voltage and current must be within the range of the MPPT Input specified in the datasheets and technical documentation of IMEON products.

Detection of photovoltaic panels

For the detection of photovoltaic panels

Open the circuit breaker between the PV and the inverter and measure the DC voltage between (+) and (-) terminals of the PV string.
NOTE: The PV DC voltage and current must be within the range of the MPPT Input. Refer to product documentation.
NOTE: Keep in mind to take into account the difference between the open circuit voltage and nominal voltage of your PV array. If you’re measuring Voc that is slightly above the inverter’s minimum MPPT input voltage, it’s very likely that the Vmp voltage will be below minimum MPPT input voltage.

How to find out the maximum PV generated power:

PV modules are subject to standard test conditions that are defined with particularly strict certifications (IEC, ISO). From idealistic radiance test conditions (1000W/m² at 25°C) result the provided voltages, currents and temperature factors that you can read from your PV modules specifications. Note that temperature plays an important role: an increase in temperature can result in modules generating less power. You must also consider all possible cable losses (PV installation) that can count for 3% and a 1% maximum in the mppt yield.

What are the priorities of IMEON solar production management?

Depending on the mode in which the IMEON hybrid inverter is programmed, the priorities for using the electricity generated by the solar installation will be as follows:

With the hybrid IMEON inverter programmed in smart-grid mode:

direct consumption of the solar production then charge of the batteries then injection to the grid.

With the hybrid inverter IMEON programmed in off-grid mode:

charge of the battery bank then supply of the loads. In this mode, dedicated to the electrification of isolated sites, it is not possible to inject energy to grid.

With the hybrid IMEON UPS programmed in back-up mode:

charge of the battery bank then supply of the loads then injectionto grid.

With the IMEON hybrid inverter programmed in on-grid mode:

all production is injected into grid.

It is possible, in the back-up and smart-grid modes, to disable the injection of electricity into the grid.
