8YF330 REVAMPING SOLAR INVERTER

EEI 8YF330 is a double stage inverter designed to perfectly adapt to a very wide range of voltages on the photovoltaic system side and therefore to be able to replace most of the centralized inverters installed in photovoltaic systems larger than 250 kWp.

The composition of the inverter also allows to guarantee high production and efficiency thanks to its structure with independent inputs which provide an independent MPPT for every 110 kWp of plant, also for utility scale systems.

The EEI revamping solution also provides as a package the replacement of the existing BT / MT step-up transformer with a new standard high efficiency transformer with 400V on the LV side, in some cases eliminating the isolation transformers present on the LV side.

EEI supports its customers throughout the revamping process by identifying the best layout with which to integrate the new inverter to have a lower impact on work and cabling on site while maintaining the existing configuration of strings, field panels and cables.

The 8YF330 inverter is compatible and certified according to the new CEI 0-16 and EEI guarantees its customers the updating of existing inverters to any updates to new versions of the standard with the least impact of on-site interventions and costs to be borne by the customer .

MPPT STRING BOOST

EEI MPPT Boost is a string optimizer that integrates the function of MPPT and combiner box in a single component. Unique on the market, EEI MPPT Boost works at the string level and not at the module level. This feature makes it easy to install, economical and efficient. In traditional systems, the different behavior of the strings forces the inverter to work on a point of the V-I curve that optimizes only some of the strings. Every single string should be optimized to collect all the energy.

EEI MPPT Boost allows you to replace existing combiner boxes and in combination with EEI Master Solar Inverter, carry out an update of the photovoltaic system, significantly increasing production and reliability compared to old and inefficient standard central inverters.

MPPT Boost can also be used in combination with EEI Master Hybrid to create hybrid industrial and power plants. The DC coupling of the photovoltaic system with the storage system in fact allows a high efficiency of the system and an extreme flexibility of operation even for off-grid installations.

Other benefits:

  • Reduction in the size of the DC cables by having constant output voltage
  • Greater efficiency between booster and inverter
  • Monitoring function of the working point
  • Different panel technologies can be used in the same system
