Your system can be protected by adding both:
surge protectors
lightning rods
Surge Protectors
These devices work to protect you from both direct strikes and voltages induced by nearby strikes. They are installed on both sides of the inverter power circuit and on any inverter communication cables. They either direct the lightning to earth or block the surges from going any further.
In our experience the most important surge protector is the one on the ethernet communications cables. So if you do nothing else - implement surge protection on any ethernet cables.
Lightning Rods
Lightning rods protect you from direct strikes. They provide an alternative, low resistance, direct route to earth so that the lightning is much less likely to go through the solar power system.
Obviously - if you install a lightning rod on your roof you need to avoid shading the solar panels with it.

home is equally vulnerable to lightening, if you are afraid of such incidence. Any other equipment, which could even be costlier than inverter, also can get damaged if you think so.
Not really, not required. Not practical and brother desired. There are far more costly electronic gadgets in home to only bother about inverter. And moreover your inverter isn't placed on roof top too to attract direct lightening strikes, so relax, it won't ever happen.
electrical wiring on the rooftops in the house. These are the ideal carriers of the surge voltages to down the house through the wiring and can damage anything or any electrical or electronic appliance coming in their way. In the houses, equipped with electrical earth conductors on the rooftop connected to the ground generally this surge voltage will pass on to the Earth without doing any damage to the other things. Many times these electrical conductors are not properly grounded and do not work for the intended purposes.
These surge voltages are of high magnitude but their duration is small and that is the reason that many times they do not damage much as they subdue very quickly.
Passing of surge voltages through electrical wiring is conducive to generation of fire and any equipment attached to these lines will only add fuel to this fire. Though electric fires in household electrical lines during thundering and lightening are rare but we have to take precautions however rare they might be.

The best way to protect an inverter from lightning is to install a surge protector. Surge protectors are devices that are designed to absorb the electrical surge of a lightning strike and protect the inverter from damage. Additionally, it is important to ensure that the inverter is properly grounded, as this will help to reduce the risk of damage from a lightning strike.
Inverters are sensitive to lightning, so they should be protected as much as possible. It would help to protect your inverter by using surge protectors and sheltering them. Still, it is advisable to switch off inverters during lightning. However, you shouldn't only switch off inverters during severe storms.
To protect an inverter from lightning, you can take the following precautions:
1. Install a surge protector or lightning arrestor on the power input lines.
2. Ensure proper grounding of the inverter system.
3. Use lightning protection devices, such as lightning rods or conductive systems, for the overall structure housing the inverter.
4. Consult with a professional electrician for specialized lightning protection measures.

Protecting an inverter from lightning involves implementing strategies to divert or mitigate the electrical surges caused by lightning strikes. Here are some measures to help protect an inverter:
1. **Surge Protectors:** Install surge protectors on both the AC (alternating current) and DC (direct current) sides of the inverter. These devices are designed to suppress voltage spikes and divert excess energy away from the connected equipment.
2. **Lightning Arrestors:** Use lightning arrestors or surge arrestors on the power lines connected to the inverter. These devices are specifically designed to handle high-voltage surges caused by lightning strikes.
3. **Grounding:** Ensure proper grounding for the inverter system. A well-designed grounding system provides a safe path for electrical currents, including those induced by lightning, to dissipate into the ground.
4. **Isolation:** Use isolation transformers or galvanic isolators to provide an additional layer of protection. These devices can help prevent the transfer of high-voltage spikes from one part of the system to another.
5. **Disconnect During Storms:** Consider implementing a manual or automatic disconnect mechanism that can isolate the inverter from the power source during severe weather conditions or when lightning is detected.
6. **Metal Enclosures:** If possible, use metal enclosures for the inverter equipment. Metal enclosures can act as a shield, directing lightning-induced currents away from sensitive components.
7. **Professional Installation:** Ensure that the inverter system is installed by a qualified professional who is knowledgeable about lightning protection measures and follows industry standards.
8. **Insurance:** Consider adding equipment protection coverage to your insurance policy to mitigate potential financial losses in the event of lightning damage.
It's important to note that while these measures can significantly reduce the risk of lightning-related damage, no system can provide absolute protection against a direct lightning strike. Therefore, a combination of protective measures and preparedness is crucial.
