For example, solar controllers such as grid-connected inverters, off-grid inverters and pumping inverters will connect electrolytic capacitors in parallel on the DC input side to support the DC voltage.
If the components are connected in reverse, the consequences are relatively serious. At best, the inverter will explode, and at worst, the components will catch fire. So special attention should be paid. If novices are not very proficient, they can first measure the voltage with a multimeter.
1. The inverter has only one string The inverter is powered by the components. If there is only one string and the positive and negative poles are connected in reverse, the inverter cannot be started, and neither the indicator light nor the screen of the inverter will light up. However, the inverter will not be damaged.
Experienced installation technicians will not make mistakes, but some novices may make the two connectors of the extension cord the same. If connected to the inverter, it will cause the positive and negative poles to be connected in reverse.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
