Update __init__.py

Fix for #110

[ryanm101]

Changed all ">", 0 to ">=", 0 as I cant think of a time where 0 would be invalid as a result of a calculation.

[treynaer]

I manually apply the change on the Battery SOC, otherwise the component cannot start when the SOC is 0.

battery_SoC = validate(decoder.decode_32bit_float(), ">=", 0.0)

About the other sensors, energy is probably only 0 when you have a new inverter/meter/battery. If 0 is detected in that case it should be ignored I guess.

@treynaer I don't own a battery myself so can't test it, but I agree that 0 should be an acceptable value for battery_Soc. With the meter values validated as >= 0, there were sometimes 'false' drops to 0 in the readings. Do you see these also for the battery Soc field with this patch applied?

[treynaer]

It's difficult to say because the battery is at this moment empty most of the time.

What I however get a lot is the following exception after allowing 0% SOC. Its good that this doesn't show op.
