rent to own solar system All-in-One Solar Energy Storage System SSI-3kW 25.6V 200Ah
Product Description: ONESUN SSI-3KW 5KWH All-in-One Solar Energy Storage System
ONESUN is proud to present the SSI-3KW 5KWH Ironbull Series, a true All-in-One Solar Energy Storage system that seamlessly integrates a solar inverter, MPPT charge controller, and a high-capacity Lithium battery into a single, compact unit . Designed for reliability in the most demanding environments, this unit serves as a small, independent solar power station, perfect for large residences, small businesses, and off-grid applications .
The core strength of the SSI series lies in its industrial-grade line-frequency isolation transformer . Unlike standard high-frequency inverters, this design provides exceptional tolerance to grid fluctuations, voltage surges, and high inrush currents. It delivers powerful instantaneous startup capability for heavy inductive loads like motors, compressors, and pumps, ensuring "no voltage drop, no downtime" performance . The built-in isolation transformer also eliminates DC components and suppresses common-mode noise, resulting in cleaner, safer power and superior compatibility with diesel generators .

Flexible Payment with PAYGO Functionality
ONESUN understands that high upfront costs can be a barrier to clean energy. Therefore, the SSI-3KW5KWH is fully equipped to support PAYGO (Pay-As-You-Go) and Rent-to-Own business models . This built-in smart feature allows end-users to access reliable power with small initial payments, making it ideal for emerging markets .
- Smart Remote Management: Distributors can send time-limited activation codes to users upon payment confirmation .
- Automated Control: If a payment period ends, the system automatically switches to standby mode until the next payment is made and a new code is entered .
This integrated technology ensures partners can expand their market reach while maintaining complete control over payment collection and asset security .
With its robust power frequency transformer, safe LiFePO4 battery chemistry, and innovative PAYGO capability, the ONESUN SSI-3KW5KWH is not just a backup power source—it is a durable, intelligent, and accessible energy independence solution for the modern world .
