Victron MultiPlus II 12/3K Thor Vegas intergration

Order was processed and shipped pretty quick install was straight forward and been running the inverter for the last 3 days and the seitch between shore power / geni power is seemless and quick great product worth the $$

It's a Victron

Five Stars to Off-Grid Source. Andrew and Rod where great. Andrew called me back when I first inquired about their products and got the ball rolling. Rod (electrical engineer) called me back and answered all my technical questions about the correct products for my installation. I could not ask for better support. The Victron MultiPlus is a great piece of equipment at a fair price. If you are installing this yourself be prepared to do alot of research on how to set it and any peripherals up correctly. Fortunately there is a ton of self help info available online.

They Stood By Me

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

Bruce D.

Awesome Service!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

Jennene A.

Real Person, Honest Service.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.

Ray B.

Easy Return

I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!

Roger V.

Totally Off Grid.

I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
