My company DC Solar Installs on a service call for a ground fault repair. This is why you must have proper clearance and properly support your PV wires. This system is being pulled off the roof due to deficiencies. The chewed conductors were resting on the rails that are grounded and burned the wires in the location of the nest!
DC solar installs installs and repairs and maintains all Photovoltaic systems in Ontario.

I show how you can get 110V from your 230V household AC supply here in the Philippines.

It turns out that Metro Manila and some other parts of the Philippines actually use two live 115V wires instead of a single 230v and neutral. With a simple hack-cable we can break out that 115V to use for 110V appliances.

I don’t know if you’d find similar wiring in other countries where 220V 230V 240V is used.

I’m not saying you should do this or that it’s necessarily safe, this was simply an experiment. You should always consult a professional electrician and check any electrical code / Meralco requirements.

This was an interesting find for me since I’m used to seeing people using heavy and expensive step down transformers to drop the voltage.
