ECI Power 200W 12V Solar Panel Kit

Off-Grid Ready, Highly Efficient, & Reliable

This Off-Grid Solar System Kit is a great option for a variety of applications, such as RVs, motorhomes, small homes, sheds, boats, remote farms, gardens, etc. (The aforementioned locations are suggestions only and do not ensure that the system will fully power your energy needs). This system can both help reduce energy costs when incorporated into an electrical system or provide free and consistent electric power to any place outside of a power grid.

This system is designed for recreational vehicles, temporary housing and small applications, not for full off-grid living and may not be adequate for your power needs. We recommend consulting with a professional first before purchasing your kit for an adequate estimate of your power demands.

ECI Power: A brand for everyone with the goal of providing an open avenue for all to know that safe lithium power should not be cost-prohibitive nor outside the scope of your project.
This Off-Grid Solar System Kit includes one 12V 50Ah LiFePO4 Battery, 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.
Economical: At a phenomenal price point, the battery is rigorously lab-tested and guaranteed to meet a minimum 2000 cycles at 80% DOD, providing high-performance longevity with a maximum of 5000 cycles at 50% DOD.
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.
Smart Tech: The controller automatically regulates charging profiles relative to ambient temperatures, providing the best level of charge in any condition and protecting against over-charge, over-discharge, overload, and short circuit. Digital Display: The unit offers an ease-of-access screen interface, displaying data ranging from state of charge to battery health.
