Proven Performance. Real Improvements. Special Pricing.
MidNite Power Inc. has changed its legal company name to Sol-Max Inc. The company, product platform, and commitment to distributors, installers, and customers remain the same. During this transition, you may continue to see existing MNP branding and model names on products, packaging, and documentation.

For a limited time, qualified participants can take advantage of the Sol-Max ESS Proven Performance Program.
