When you have solar panels, your primary concern is to make the best use of them. As we all know, solar energy generated by the PV panels is better to not use directly but to go through the solar power inverter. So, it\u2019s important to make the correct connection between solar panels and the solar inverter. This page will help you solve the question of how do I connect the solar panels to the inverter.<\/p>\n

1. Which wiring connection is better?<\/strong><\/h2>\n

As we know, the ways of\u00a0solar panels connection<\/a>\u00a0are in series and in parallel. But which connection is better for solar panel systems? Let us make a comparison.<\/p>\n\n\n\n\n\n\n
Feature<\/strong><\/td>\nIn Series\u00a0<\/strong><\/td>\nIn Parallel<\/strong><\/td>\n<\/tr>\n
Advantages<\/td>\nIncreasing voltages and the same current<\/td>\nIncreasing currents and the same voltage<\/td>\n<\/tr>\n
A single wire to the grid<\/td>\nOne of the panel broken and the rest panels work well<\/td>\n<\/tr>\n
Disadvantages<\/td>\nOne of the panel broken and all panels work failure<\/td>\nMultiple wires to the grid<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

With the way of connection in series, the most outstanding feature is that it can increase the voltages of the whole solar system and keep the same current, while no need bigger cable to the grid. But when one of the panels gets wrong, the solar panel system will collapse unless you fix it or update a panel.However solar panel wiring in parallel connection can keep the voltage contain and increase the current. And when one of the panels works badly, the solar panel system can still go properly function but just the power will go down. The disadvantage of parallel wiring is to need multiple wires when connecting into the grid.In fact, to balance voltage and amperage\u00a0for your solar array to perform at the\u00a0best,\u00a0many electrical applications\u00a0use solar panel wiring not just in series or\u00a0in\u00a0parallel, but a hybrid of both in series and in parallel connection. The number of series panels depends on the\u00a0voltage\u00a0of the\u00a0load, and the number of parallel panels depends on\u00a0the power\u00a0of\u00a0the load.\u00a0But also need to meet the solar power inverter\u2019s condition of normal operation at the same time.<\/p>\n

2. Can I connect the solar panel directly to the inverter?<\/strong><\/h2>\n

Yes, solar panels can be directly connected to the inverter instead of the charge controller. A proper and good quality solar power\u00a0inverter is an essential part of your\u00a0photovoltaic arrays. It\u2019s an important bridge of\u00a0solar panel connection to the battery<\/a>\u00a0and to the grid. The solar power inverter has four special functions:1)\u00a0It can average\u00a0the voltage fluctuations of the solar panels and output a steady charging voltage2)\u00a0It can prevent battery overcharging and prevent backflow.3)\u00a0It can convert\u00a0the DC current from the solar panels into AC current to support domestic\u00a0appliances and export to the grid.4)\u00a0It has the function of monitoring the photovoltaic panels, the battery, the grid, and your loads with maximum power point tracking\u00a0and anti-islanding\u00a0protection.The solar system connection diagram is below.<\/p>\n

3. How to connect the solar panel to the solar power inverter?<\/strong><\/h2>\n

About the solar panel connection to inverter wiring steps, let me show you the luxpower hybrid inverter because the PV connection of luxpower hybrid inverter is the same as a traditional on-grid solar inverter(string inverter).<\/p>\n

* When connected solar panels to the inverter, take notice that:<\/strong><\/h3>\n

1) Before connecting the PV, please use the muti-meter to measure the PV array voltage to verify if the PV array is working normally, if not, please fix the PV array to normally working states before connection.<\/p>\n

2) Inspect the PV+ and PV- output of the PV string, make sure the positive and negative poles of PV and inverter will be correctly connected.<\/p>\n

3)\u00a0When your PV panel’s ambient temperature could possibly be lower than 0\u00b0,\u00a0then please check the PV array voltage up the ceiling, and if you are not sure please ask your system or panel provider for further assistance. As when the temperature is extremely low the PV panel voltage will increase by a certain percentage.<\/p>\n

* Solar panel wiring steps:<\/strong><\/h3>\n

Step 1: Turn off or disconnect the PV switch(DC switch). Then keep this switch always open during the connection.<\/p>\n

Step 2: Assemble the PV connector1)\u00a0Strip 6-8 mm insulation from the cable end.<\/p>\n\t
