Most modern inverters will display reversed polarity as a negative voltage—this is normal. If the inverter faults immediately, double-check your terminal connections. When polarity is reversed, current flows in a direction the inverter's internal. . The inverter is what could be potentially damaged. Its hard to say exactly what will happen. After replacing them it did function again and actually worked for more than a year. It was cheap garbage so I'm. . When you reverse the polarity of solar panels—connecting the positive terminal to the negative side of the system and vice versa—the consequences range from inefficient operation to catastrophic equipment failure. Experienced installation technicians will not make mistakes, but some. . I picked up an Ampace Andes 1500 solar generator to use as an emergency backup power source for a forced air gas furnace. Plugged it all in (Andes 1500 has pass through AC) and the thermostat and blower fan run but no heat to be had.
