Its no news today that the batteries of your inverter or solar system are the life of the system. They are also the major cost component of the system and the one part of the unit that may need replacing from time to time.
Now the cost of these batteries are pretty high...
The main selling point of inverters isn't the FACT that they save you money or that they could replace your generators or that they provide power without noise or that they run without a fuel like petrol or diesel.
Most people don't realise it but lighting in our homes and offices account for a large part of electricity load consumption. Yes we all say that we are using energy saving bulbs but I ask you this, are you using the right ones.
