PAYG Solar Home Storage Systems

S80

Shengxin S80 PAYG Smart Solar Home System

Purpose-built for African off-grid markets — the S80 integrates a token-based PAYG (Pay-As-You-Go) keypad lockout controller directly into the unit. Distributors issue 30-day activation codes to end-users, enabling up to 12-month installment plans while eliminating default risk. Combined with a 150 W pure-sine inverter, 80 Wh LiFePO₄ battery, and MPPT solar input, this is the most bankable solar home system for emerging markets.

Key Features

The All-in-One Solar Kit You’ve Been Waiting For

Inverter, battery, charge controller, and display — integrated into one compact, affordable box.

PAYG Keypad Lockout System

Built-in physical keypad with token-based activation controller. End-users enter a unique 30-day unlock code — distributors issue new tokens upon installment payment. Supports up to 12 monthly locking cycles, effectively eliminating default risk for off-grid financing programs.

Built-in 150 W Inverter + LCD

Pure sine wave AC output powers fans, LED TVs, laptops, and routers. Integrated backlit LCD displays real-time battery %, wattage, and remaining runtime — no external inverter or separate monitor needed.

30 W MPPT Solar Ready

30 W polycrystalline panel input with Maximum Power Point Tracking — 30% faster solar charging vs. PWM controllers. Full recharge in 3.5 hours of direct sunlight.

80 Wh LiFePO₄ Battery + BMS

Lithium iron phosphate chemistry — 3 500+ cycles, superior thermal stability, zero thermal runaway risk. 8-layer BMS: over/under-voltage, over-current, short-circuit, over-temp, reverse polarity, cell balancing, and ground fault protection.

Purpose-Built for Africa

110V/220V dual-voltage selectable. Tropicalized PCB coating against humidity and insects. Works reliably from 0 °C to 55 °C ambient. Compatible with all major African PAYG software platforms via USB token bridge.
