ExpertPower 200W 12V Solar Power Kit | 2 x 12V 20Ah LiFePO4 Lithium Batteries | 200W Mono Rigid Solar Panels, 20A MPPT Solar Charge Controller | RV, Trailer, Camper, Marine, Off Grid, Solar Projects

LiFePO4 battery provides 2500 - 7000 cycles & a 10 years lifetime with built-in Battery Management System (BMS) protects it from overcharge, deep discharge, overloading, overheating and short circuit, and excessive low self-discharge rate ensuring up to 1 year maintenance-free storage.

Built-in low-temp cut off prevents charging under 23 °F (-5 °C).

This Off-Grid Solar System Kit includes two 12V 20Ah LiFePO4 Batteries, two 100W Monocrystalline Solar Panels and one 20A MPPT Solar Charge Controller with Bluetooth Adapter, one pair 10ft 12AWG MC4 Solar Cables, one pair 6ft 12AWG Battery Cables and two sets Solar Panel Mounting Brackets and one set Y Branch Adapter Cable.

System Detect: The 20A MPPT controller automatically recognizes 12V and 24V systems for quick setup and utilizes modern solar technology to maximize your solar array's power generation by over 20% through sophisticated tracking and capture compared to PWM with auto-detects 12V/24V systems.
