is LM350 perform as a voltage regulate? or which part need regulating as u means? this circuit does not have any controller to stop the voltage when the battery is full charging, may b i make a switch button so that i can switch off the charging, or do u have any circuit to auto switch off the charging?Lefty.
The OP, among other things in his (her) circuit needs is regulating. Part of any charging circuit, mechanical or solar needs a way to stop. The dump load is part of that circuit.
