PRODUCT OVERVIEW
The MidNite Solar Rosie 48V is a pre-wired, all-in-one off-grid inverter/charger system built for reliable home and cabin power. It provides 7000VA of continuous power and 15,000VA of surge capacity, enough to start motors and run heavy appliances. Because it has zero transfer time, your power doesn't flicker when the system switches between sources.
The modular, pre-wired design simplifies installation compared with assembling an off-grid system part by part. Real-time battery monitoring, programmable automation, and auto generator start are all built in. It's American-made, comes with a 7-year warranty, and was designed by engineers with more than 100 years of combined renewable energy experience.

SMART FEATURES
The built-in MidNite Wizbang Jr. and MNGP2 display show your battery's state of charge in real time, and an easy-turn dial lets you navigate settings. Two auxiliary terminals offer 15 programmable options each, so you can automate tasks like load shedding or triggering other equipment based on battery conditions.
When your batteries run low, auto generator start fires up a compatible two-wire generator to keep power flowing. The 60A transfer relay on each leg switches sources with zero transfer time, so connected electronics never notice the change.
