Using Solar battery for DAC and Pre-amp


I did a minor science project yeasterday. I used Solar panel to charge my solar pure sine wave inverter battery at day time. Then I used the battery to power my Oppo 205 anb Sennheiser earphone amp. The result is super. A day sun shine will charge 100% of battery. Then I have 5 hr of of energy to power my audio equipments. The 12V to 110V pure sine wave inverter battery gives much clean power source (no noise for power grid) and it's 100% carbon free clean energy. I urge audiophile to explorer this option of new energy source: clean and pure.

Good for you junzhang10! Nothing better than battery power for a low-current device!
I think there was someone on here that uses a batter power supply and solar to power their whole system. if memory serves He used a goal zero Yeti and clamed it was very good. and powered his system for many hours.  

it intrigues me as i have bad power in my building  and the thought of being off grid for my system is an intriguing thought.

You can still charge your solar battery with 110V AC during rainy days and still beable to use the pure sine wave power source your low current components.
