So one "solution" is a variac or auto transformer, with the realisation that if mains goes high the output will go very high. A "safer" alternative is a UPS or inverter run permanently - assuming it is rated to do so. You can also get mains conditioning units which automatically adjust output voltage - usually specialist and expensive. - Download [PDF]

It has metering, lightning protection, reverse power protection, telemetering, telesignalling, and other features. After connecting the solar panel with load or power grid, the power distribution cabinet can form an independent power system, grid - connected system, or hybrid system, and it can supply power to the AC and DC load simultaneously.
In addition, the high PV penetration in the low voltage (LV) network may cause some power quality challenges (Alquthami et al., 2020). Some of the main issues due to high PV penetration are ...
The old-fashioned way of determining whether the cabinet is electrified (or hot) was to brush it with the back of the hand. With the advent of the AC detector, this is no longer necessary or advisable. Knock on the cabinet to notify any inhabitants (wasps, mice, spiders, and even snakes) that you are coming in. Be sure to have insect spray handy.
When deciding between high voltage and low voltage solar panels, keep in mind that higher voltage systems are more efficient in general for your off-grid solar power system. A 48V system is the most efficient and cost-effective per watt-hour generated as compared to 24V and 12V systems.

If the nearest transmission line to your property has a voltage of, say, 115 kV (115,000 volts), the output voltage from the solar farm needs to "step up" to 115 kV to feed power into it. Likewise, the power that line carries to a neighborhood 50 miles away eventually needs to "step down" in voltage so that homes can use it.
