Build a 1kW WiFi MPPT Solar Charge Controller, equipped with phone app datalogging telemetry! (Android & IoS) It is compatible with 80V 30A solar panel setups and all battery chemistries up to 50V. The project is based on an Arduino ESP32 and runs on my Open Source Fugu MPPT Firmware! Total project cost is roughly around $25 (sourced from the Asian market). It is significantly cheaper than buying ready made $200 MPPTs

What Is An MPPT And Why It Is Important To Solar Panels?

Maximum power point tracking (MPPT) is a technique used with energy sources with variable power, like solar panels, to maximize energy harvesting! An MPPT solar charge controller is an essential device for solar setups. MPPTs are intelligent DC-DC converters. They regulate current and voltage to safely charge batteries and power inverters. Aside from regulation an MPPT uses a clever algorithm that tracks a solar panel’s maximum power point. The proper explanation gets technical but the easiest way to put it

“Using an MPPT for solar, helps you gather the most energy your solar panels can provide”

High Efficiency Synchronous Buck Design

Synchronous buck based MPPTs are one of the most dense and energy efficient designs. Premium commercial grade MPPTs use the same circuit topology. It turns out, you are not paying for the materials but rather for a company’s R&D costs. Building one is cheap, but producing a proper design takes a lot of work.

One Of The First Tutorials To Uncover A Problem-Free Synchronous MPPT Design

For years, the DIY community has made several attempts on building a True Synchronous Buck MPPT but is often met with serious problems. This tutorial will walk you through on how I implemented a fix to the age old problems that has plagued most DIY MPPT attempts on building a high-power MPPT. It will also walk you through on building my 6-month lab tested beta MPPT design.”
