Are you interested in a DC powered off-grid home? I want to convince you that building an off-grid solar powered DC home is viable.
Most modern electronics run off DC. For efficiency and longevity, most pumps and fans are electrically commutated motors (motors that generate their own AC signal )
Greater Efficiency
Reliability - The most complicated piece of equipment in the traditional solar install is the inverter. An all DC design prevent an inverter failure from bringing the whole system done.
Simplicity and self reliance.
