Not Sure This Is The Right System?
Request a Free Solar ProposalGenerate and store solar energy with the SunGold Power 12kW Hybrid Solar Kit. This system combines a SGS-12K18MAX hybrid inverter, 20 × 450W bifacial solar panels, and your choice of 16.07kWh, 32.14kWh, or 48.21kWh PowerMax battery storage. Designed for home backup, solar energy storage, and off-grid applications, it provides 9,000W of rated solar array capacity and 120/240V split-phase output.

12kW Hybrid Inverter - Provides 12,000W rated output at 240V for compatible household appliances. Available power depends on battery discharge limits and solar production.
9kW Bifacial Solar Array - Includes 20 × 450W N-Type bifacial panels, capturing sunlight from the front and reflected light from the rear. Actual production depends on sunlight and installation conditions.
Your Choice of Battery Storage - Select one, two, or three PowerMax batteries for 16.07–48.21kWh nominal storage, helping power appliances after sunset or during outages.
200A Grid Pass-Through - Supports 200A continuous utility pasthrough in bypass mode. This is separate from the inverter’s rated solar and battery output.
Outdoor-Rated Components - The inverter and batteries feature IP65-rated enclosures for suitable indoor or outdoor installations, following manufacturer requirements.

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!

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.

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.
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.
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.
