1. Off-grid - Power a home or small business that has no grid access

2. Weak-grid - As a back-up to have on standby to keep business or home life going even when power is gone

3. Two charging options - charge from the grid or from the sun depending on whether you're on-grid or off-grid

4. AC and DC - can power both AC and DC appliances, meaning you don't need to replace your existing product, you can just power them in a more affordable, safe, stable, and cleaner way.
