I believe "current" is the rate of flow I believe "watts" volume of mass I believe "volts" is the force Then again I am not sure. Then again all the above are means to measure something from different points of view while not understanding/explaining what "it" is.

I recently moved houses and the previous owner had a sunny boy sb-2000hf-30 inverter installed. The first green light is on but when I tap on the screen nothing happens. On the manual it says that tapping/knocking on the screen should turn it on. Anyone knows how this inverter works?

We have a solar iboost which was working fine then suddenly stopped. If you turn it off at the mains and then on again, it says low voltage and heats via solar initially with a high reading then this drops until zero and it states heating off. Amy ideas on what the problem could be? Thanks
