On-Grid Inverter
R3 Navo
30kW / 50kW | Three Phase, 3/4 MPPTs
RENAC R3 Navo Series inverter is especially designed for small industrial and commercial projects. With fuse free design, optional AFCI function and other multiple protections, it ensures higher safety level of operation. With a max. efficiency of 98.8%, a maximum DC input voltage of 1100V, wider MPPT rangeand a lower start-up voltage of 200V, it guarantees an earlier generation of power and a longer working time. With an advanced ventilation system, the inverter is dissipated heat efficiently.

Cause of occurrence:
Too many modules are connected in series, causing the input voltage on the DC side to exceed the maximum working voltage of the inverter.
Solution:
According to the temperature characteristics of PV modules, the lower the ambient temperature, the higher the output voltage. It is recommended to configurate the string voltage range according to the inverter datasheet. In this voltage range, the inverter efficiency is higher, and the inverter can still maintain the start-up power generation state when the irradiance is low in the morning and evening, and it will not cause the DC voltage to exceed the upper limit of the inverter voltage, which will lead to the alarm and shutdown.
Cause of occurrence:
Generally the PV modules, junction boxes, DC cables, inverters, AC cables, terminals, and other parts of the line to ground short-circuit or insulation layer damage, loose string connectors into the water, and so on.
Solution:
Disconnect the grid, and inverter, check the insulation resistance of each part of the cable to the ground, find out the problem, and replace the corresponding cable or connector!
Cause of occurrence:
There are many factors affecting the output power of PV power plants, including the amount of solar radiation, the tilt angle of the solar cell module, dust and shadow obstruction, and the temperature characteristics of the module.
System power is low due to improper system configuration and installation.
Solutions :
(1) Test whether the power of each PV module is sufficient before installation.
(2) The installation place is not well-ventilated, and the heat of the inverter is not spread out in time, or it is exposed to sunlight directly, which causes the inverter temperature to be too high.
(3) Adjust the installation angle and orientation of the PV module.
(4) Check the module for shadows and dust.
(5) Before installing multiple strings, check the open-circuit voltage of each string with a difference of no more than 5V. If the voltage is found to be incorrect, check the wiring and connectors.
(6) When installing, it can be accessed in batches. When accessing each group, record the power of each group, and the difference in power between strings should not be more than 2%.
(7) The inverter has dual MPPT access, each way input power is only 50% of the total power. In principle, each way should be designed and installed with equal power, if only connected to one-way MPPT terminal, the output power will be halved.
(8) Poor contact of the cable connector, the cable is too long, the wire diameter is too thin, there is voltage loss, and finally cause power loss.
(9) Detect whether the voltage is within the voltage range after the components are connected in series, and the efficiency of the system will be reduced if the voltage is too low.
(10) The capacity of the grid-connected AC switch of the PV power plant is too small to meet the inverter output requirements.
