Description

DIY 1kW Open Source MPPT Solar Charge Controller

Build a 1kW 80V 30A WiFi MPPT Solar Charge Controller, equipped with a phone app datalogging telemetry! (available on Android & IoS) The design has been intensively tested for months and has been the first fully open source, problem free, Truly Synchronous Buck MPPT design.

Synchronous buck based MPPTs are one of the most energy efficient designs. Premium commercial grade MPPTs use the same circuit topology. By replacing diodes that cause voltage drops in a buck converter (which results to additional power losses) with low on-resistance N-channel MOSFETs, power losses are decreased significantly. For years, the DIY community has made several attempts on building a True SyncBuck MPPT but is often met with fatal problems. Other got it to work but somehow cheated by still adding diodes, which results to significant losses. So I went on a journey and collaborated with Open Green Energy and countless co-leagues to deliver a problem free SyncBuck MPPT design for open-sourcing, which lead me to make this 4 Part video tutorial.

SPECS:

- MPPT Perturbed Algorithm With CC-CV

- 80V, 30A Input (Solar, Wind Turbines, PSU)

- 50V, 30A Output (Li-ion, LifePO4, Lead Acid & etc.)

- 98% Peak Conversion Efficiency (Synchronous Buck)

- WiFi & Bluetooth Blynk Phone App Telemetry

- Charger/PSU Mode (can operate as a programmable buck converter)

- 16Bit Precision ADC Measurements (ADS1115/ADS1015)

- Automatic ACS712-30A Current Sensor Calibration

- Battery & Input Disconnect Recovery Protection Protocol

- LCD Menu Interface (with settings & 4 display layouts)

- Flash Memory (non-volatile settings save function)

- Settable PWM Resolution (8bit-16bit)

- Settable PWM Switching Freq (1.2kHz - 312kHz)

Hello, this project is very popular, and many electronics enthusiasts have placed assembly orders. We assemble it for you according to the author's BOM. After you place an order, we will send you a BOM quotation. We will purchase components and assemble it only after you confirm that there is no problem. You can select PCB+Assembly in the upper right corner, then click Add to cart in the upper right corner, enter the quantity you want, and there will be an estimated time after placing the order.

I am from Bangladesh. I am new user of pcbway. Please tell what is pcbways delivery system in Bangladesh and delivery time, costs etc. i want to make this project but components are not available in local shops. I want to order assembled pcb but i am affraid for is there any customs taxor not. if someone from BD ordered this board please responce.

Our logistics to Bangladesh are all tax-exclusive, DAP, commonly used logistics are DHL, FedEx-IP, Bangladesh will charge tax regardless of the value of the package, so there will definitely be tariffs. For the cost and delivery time, you can click Add to cart in the upper right corner, then enter the quantity you want, and click Calculate, then click Save to cart, and an estimated price and delivery time will appear. The final price and delivery time are subject to the review.

I've been waiting a long time for a project like this, have used EpEver MPPT and the Australian Jaycar equivalent a number of times in RV/Motorhomes for myself and a coupe of friends. They work OK most of the time but are very hard to debug and lately I cannot control them from my Android phone (support seems to have stopped at A8) Intellectually I can follow the project quite well, code is no problem I have 50years experience as a Software developer, hardware wise my electronic training dates back to valve techniques, With age my manual dexterity has suffered greatly, so soldering tiny circuits is not likely to be successful, I would love to buy an almost complete assembly and take it from there, IS THIS possible. BTW I cant get the Google Drive downloads to work despite having the third party cookies enabled!

Very cool design. I'm thinking, at least for my use case, of doing away with the ESP32 and making it into a form factor so it can fit on a RPi, Arduino, or BBB.

Has anyone figured out a way around the dead Blynk phone app issue? This is a complete stop for me on this project. I have boards, components, and 3D printed items ready, but will not do any further work until I can come up with a resolution for the closure of the BLYNK application.

Is this project still supported? It has taken me some time to get PCBs made and locate the parts. However, if it is no longer supported or even active, I am not sure that I want to try to go forward.

Hey, I am also looking to get this project for my pv system. I would like to order the board with components assembled but I don't find the pick and place file anywhere in the source of the project... Is it really possible to get the project fully assembled directly from PCBway?
