People who are using Power inverters or UPS at home or office to supply backup to appliances and electronic devices may face this problem that their power inverter or UPS fails to cut off charging causing battery to overcharge and get hot. Usually when boost charging is complete, charger turns on trickle or float charging. Float charging sustains the battery voltage and does not let it drain.

The most common cause is because the input voltage source is too high. Then measure the input voltage or check the DC bus parameter at fault (you can check this parameter in the monitor parameter set of the inverter). Input overvoltage of the inverter is usually caused by a problem with the substation that increases the voltage at the inverter.

Final Thoughts. High voltage panels are great for people who live in an area where the sun is blocked by clouds frequently. Low voltage panels, on the other hand, don't have to be connected up with a regulator as they can generate power even if there isn't any sunshine. A low-voltage solar panel has much lower start-up costs than a high.

Inverter units appeared on the market during the second half of the 1970s. In a primary- switched inverter unit (see Figure 5.8), the 50 Hz mains supply is first rectified and then, using power semiconductors, is turned back into AC at a higher frequency, usually in the range 5-100 kHz. This reduces the weight of the transformer and inductor to a fraction of what is needed for a 50 Hz unit.

The problem with a traditional string inverter is that the solar system can only produce as much electricity as the least productive panel. If one panel goes down, so do the others. For example, you have eight solar panels on your roof and seven of them are producing at full efficiency.

Two significant problems occur when you hook up your RV using a long or skinny (or both) extension cord. The first is that this "electrical friction" causing the voltage drop makes the wire itself heat up. And it can heat up to the point where it gets limp and catches on fire. The second problem is that your RV is only getting 100 volts of.
