I was searching for solar companies online and got quotes from several of them. I evaluated them not just based on their price, but also how much information those people giving me the quotes could give me about why they were choosing that system. I decided to go with A1 Solar by my impressions of how organized they were. I had another company that I was looking at who failed to get back to me in a timely manner several times, and so I eliminated them.

I was really impressed with their salesperson and they knew what they were doing. They’re an excellent company to work with.

It has the option to use it off-grid only, just solar panel and battery

No this is on-grid inverter. You need off grid or hybrid inverter
I am replacing a dead unit (same spec, older Xantrex 3.8). Can I buy this from you for myself or do you only sell to contractors?
