/diy/ - Do It Yourself

Have you made any calculations on the power needed from your solar cells?

The amount of energy that you need to store?

Most of your appliances (all), a regular (pwm) sine inverter would be sufficient as all have switch mode power supplies. this type of inverter is also more efficient.

Why use such high capacity batteries, rather connect several in series, with lower capacity, this way you reduce losses and wire gauge

conduction losses is P_loss = Ohm * Current^2
Where Power is P_con= Volt * Current
Energy stored in batteries is also E_stor = V * Ah

Notice the ^2 this is something that makes losses rise fast..

Find a DC/AC converter that supports 100 - 155V, this way you have higher efficiency, and lower currents in your inverter.

Your solar cells should also be connected to an individual boost / flyback converter with PPT for optimum efficiency.

As for heating, I would recommend a heat pump, or some solar heater panel, perhaps build together with your solar panels.

- this could be done by a thin sheet of glass above your solar cell, and thermally insulating the a box around it, then making cold air enter one side and sucking warm air from another side, this air goes the wan then...

as for vehicle I would recommend a Mercedes Sprinter.
