Having finally got a nice 4 channel scope, i now am missing the ability to sample current data from test devices. High bandwidth current probes are obviously very expensive, but generally, for what i am doing, i don't need a very high current sampling rate (as inductance tends to limit ...
Less than 100% reliability is essential for the sustainability of an off-the-grid solar system, because above a certain threshold the fossil fuel energy used for producing and replacing the batteries is higher than the fossil fuel energy saved by the solar panels. Apart from sustainability (and...
