Enhancing Winter Performance: Inverter Management in Cold Weather

Enhancing Winter Performance: Inverter Management in Cold Weather

Navigating the challenges of winter conditions is crucial for photovoltaic systems, especially inverters. In a recent Solis seminar, experts shared insights on optimizing inverter performance in low-temperature environments.
Solis Seminar [Episode 56]: Online O&M dispersion analysis

Solis Seminar [Episode 56]: Online O&M dispersion analysis

PV plants are an incredible asset with long-term income. Their construction is quick, but the time required for operation and maintenance is more than 25 years. Compared with small PV plants, the number and scale of large PV plant components are very big, and late O&M and troubleshooting are increasingly difficult. There can also be an accumulation of problems with equipment selection, construction quality, etc. in the early stage. These factors will affect the revenue of power generation in the later stage of power plant operation. This Solis workshop will focus on how to use digital tools to assist daily operations.
Solis Seminar [Episode 55]: Using the piecewise method to check the PV string ground point

Solis Seminar [Episode 55]: Using the piecewise method to check the PV string ground point

As the running time of PV plants increase, the DC line slowly ages, and the waterproof performance of the DC terminal (MC4 terminal) deteriorates. As a result, the insulation impedance of the DC line is too low, or the positive and negative terminals are short circuited to the ground. Either way, major failures may occur, affecting the generation of electricity. It may be difficult for inexperienced power plant O&M personnel to exclude grounding PV string or to find the point of grounding PV string. This Solis seminar will share a method of locating ground fault points to improve troubleshooting speed and cut down on manpower.
The Benefits of PV + Energy Storage Systems

The Benefits of PV + Energy Storage Systems

PV systems have become a reliable source of clean energy by utilizing energy storage units. In many countries and regions, PV + storage systems have become the preferred source of energy for a variety of reasons.
Solis Seminar, Episode 49: Influence of Azimuth and Tilt on Yield of PV System

Solis Seminar, Episode 49: Influence of Azimuth and Tilt on Yield of PV System

The tilt and azimuth of a solar panel greatly influence the energy yield of the overall system. The same panel, at the same installation site, can have different azimuth or tilt. This is a topic we are often asked about so in this Solis seminar, we explore the subject further.
Solis Seminar, Episode 46: Ensuring DC Polarity is Correctly Connected

Solis Seminar, Episode 46: Ensuring DC Polarity is Correctly Connected

With the advancement of carbon reduction goals and the intensification of the global climate and energy issues, the installed capacity of clean energy is increasing sharply. As one of the main forces in the field of clean energy, solar power generation has performed well in the past two years. Capacity has soared and construction volume on site has increased significantly, resulting in a large increase in the proportion of DC polarity reversed faults. This episode of Solis Seminar will share with you the problems related to reverse polarity of DC power and how to prevent it.
Solis Seminar, Episode 36:  The influence of winter on Solar PV system operation and related O&M considerations

Solis Seminar, Episode 36: The influence of winter on Solar PV system operation and related O&M considerations

Winter is well and truly on its way for the northern hemisphere with temperatures beginning to fall and already reaching the freezing point in some regions. According to forecasts there will be prolonged periods of icy and snowy weather in Europe on its way. So, what are the specific effects of winter on the operation of a solar PV system, and how should we carry out effective operation and maintenance (O&M) of the PV plant in cold weather?
Correct Use of Aluminum Core Cables in PV Systems

Correct Use of Aluminum Core Cables in PV Systems

Grid transmission cables are usually aluminum core. Therefore, in the construction of PV plant projects in residential and commercial areas (especially household PV plants), many users will use aluminum core cables to directly interface with inverter output ports or circuit breakers ports. This can cause many safety problems. This Solis seminar will share with you the correct connection of copper and aluminum cables.
Solis Seminar, Episode 27 : How does a single-phase inverter connect to split-phase grid?

Solis Seminar, Episode 27 : How does a single-phase inverter connect to split-phase grid?

In some special countries and regions, the grid structure involves split-phase grid, but if there is no split-phase inverter when installing PV system, can the conventional single-phase inverter be connected to the grid? What problems should we pay attention to? We will share them with you in this Solis seminar.
