Product Description:
Unlock the full potential of your solar energy system with the EG4 100A Output Charge Controller, engineered with advanced MPPT technology derived from the proven EG4 3kW All-in-One Solar Inverter. This unit offers a seamless balance of efficiency, affordability, and durability—making it an ideal solution for both residential and commercial solar setups.
The EG4 100A Output Charge Controller is designed to efficiently capture and convert solar power from your PV array, safely optimizing it for charging your 48V battery bank. With a maximum charging current of 100A, this controller can rapidly charge a 5.12kWh battery in approximately one hour, ensuring minimal downtime and maximum energy availability.
Thanks to its wide PV voltage input range, there's no need for external combiner boxes, and with a max open-circuit voltage of 500VDC, it can handle large PV arrays with ease. Built-in protection mechanisms—such as PV and battery breakers—ensure safe operation in all conditions.
Whether you're upgrading an existing installation or building a new system from the ground up, the EG4 100A Output Charge Controller is an essential component for maximizing solar efficiency and energy harvesting.
Maximum Power Point Tracking (MPPT) for optimal solar power conversion
500VDC max open-circuit voltage allows for high-voltage PV arrays
Supports up to 5500W of usable solar array power with branch connectors
22A max string current, perfect for high-output solar modules
Adjustable 0-100A charging current (default set to 80A)
Charges a 5.12kWh EG4 battery in ~1 hour at full 100A rate
48V nominal battery support, with a charging voltage range of 48-62VDC
94% maximum efficiency with low self-consumption (<25W)
Built-in DC disconnect and battery breakers for safety
Communicates with EG4 batteries via RS485 BMS port

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
