Product Overview

The Enphase IQ Battery Base Kit Four B03-T01-US00-1-3 with Single B03T-C-0430-O and Large B10T-C-1290-O Cover is a bundle built around Enphase IQ Battery 3T base units and the matching cover kits used to complete the enclosure assembly. Each B03-T01-US00-1-3 base unit is the 3.36 kWh IQ Battery 3T base module with integrated grid-forming microinverters, while the B03T-C-0430-O cover kit provides the cover, wall-mounting bracket, and required mounting hardware for a single 3T unit. The B10T-C-1290-O large cover kit adds the cover, wall-mounting bracket, and interconnect wiring needed for daisy chaining the three battery units in the larger 10T configuration.

This bundle is ideal for projects that need a mix of 3T and 10T cover components in the same Enphase storage architecture. The included base modules deliver compact AC-coupled storage capacity, while the cover kits complete the system mechanically and electrically so the battery units can be installed as intended by Enphase.

Key Benefits

Four Base Units Included: The bundle includes four B03-T01-US00-1-3 battery base units, giving installers the core storage modules needed to build Enphase IQ Battery systems with consistent component sourcing.

One 3T Cover Kit Included: The B03T-C-0430-O cover kit supplies the cover and wall-mounting bracket required to complete an IQ Battery 3T-style enclosure.

One Large 10T Cover Kit Included: The B10T-C-1290-O cover kit includes the cover, wall-mounting bracket, and interconnect cabling for daisy chaining battery units in the larger 10T configuration.

Flexible Project Packaging: This bundle helps simplify procurement when a project requires a combination of base units and both small and large cover components rather than purchasing each item separately.

Enphase System Compatibility: All parts in the bundle are aligned with Enphase IQ Battery storage system architecture, helping ensure the components fit together as designed.

How It Works

The base units provide the storage and inverter hardware, while the cover kits complete the physical enclosure and internal wiring. In practice, installers mount the battery base modules, add the matching cover components, and then connect the interconnect wiring where applicable. The result is a finished Enphase battery system that matches the intended module and enclosure configuration.

Base Module Function: The B03-T01-US00-1-3 units form the storage foundation of the system.

Cover Kit Completion: The cover kits finish the installation and secure the battery assembly.

Interconnect Wiring: The large B10T-C-1290-O cover supports wiring between battery units in the larger stacked configuration.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

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.

Jacob B

Easy Process, Genuine Support

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.

Patrick B

Off Grid Solar Purchase

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!

James Martin

Highly Recommend

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.

Brian H

Solar Kit for Mobile Work Van

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.

Keith S

Best Tech Support

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!

Coll A

Great Experience

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.
