Harnessing the Sun: A Guide to DIY 3000 Watts Solar Power for Long-Term Power Outages
DIY 3000 Watts Solar Power – Hey, guys. Today, I’m going to show you how I built this portable power system for providing off-grid and emergency backup power. This is the second version of the hand truck-based portable power system I’ve built. This one features a 5000-watt-hour lithium iron phosphate UL-listed battery and a 3000-watt pure sine wave inverter.
Are you tired of being left without power during natural disasters or unexpected power outages? A portable solar power station may be just the solution you’ve been looking for. In this article, we’ll walk you through the process of building a 3000W portable solar power station, perfect for providing off-grid and emergency backup power during extended power outages.
Featured Products
Before we dive into the building process, let’s take a look at the featured products we’ll be using in this build. We’ve selected a 5120Wh UL-listed lithium iron phosphate battery and a 3000W pure sine wave inverter from Growatt, respectively. These high-quality components will ensure reliable and efficient power output.
I’ll be using the EG4. this is a 48-volt battery the LiFePO4 model it has 100 amp hours or just over 5,000 watt-hours of power and an interesting fact about this battery is it’s now ul listed when I did the original review video they didn’t have that certification yet but they do have it now.
And then for the inverter, I have the GrowWatt SPF 3000. it’s a 48-volt inverter 3000-watt pure sine wave inverter. It’s got an 80 amp built-in MPPT charge controller and a 40 amp AC charge controller and this is the first time I will be using the Grow Watt inverters up until now. I’ve pretty much been exclusively MPP solar however these GrowWatt inverters are becoming increasingly popular on the DIY market they do look strikingly similar to MPP solar’s products the internals are likely mostly the same.

Installing the Battery
The first step in building our portable power station is installing the battery onto the hand truck. We opted for the EG4 Battery which is a 48V, 100Ah server rack battery with an impressive 10-year warranty. To secure the battery onto the hand truck, we used heavy-duty zip ties around the handles.
Mounting the Inverter
Next, we need to mount the inverter above the battery. Since there isn’t much space on either side of the inverter to secure it to the hand truck, we used pieces of unistrut channel at the top and bottom of where the inverter will sit. This will allow us to bolt the inverter down securely.
DC and AC Cabling
With the battery and inverter in place, it’s time to connect them using DC cabling. We used 4 AWG pure copper battery cables from Current Connected, which are single jumper cables for easy installation. For the AC wiring, we used a 20A power strip to connect our devices.
PV Solar Input
A crucial aspect of a portable solar power station is the solar input. We used MC4 cables to connect the solar panels to our system. It’s important to ensure that all components are properly wired and connected to avoid any potential hazards or malfunctions.

First Startup
After completing the wiring and connections, it’s time for the first startup of our portable power station. We need to configure a few settings on the inverter, such as input voltage and frequency, to ensure seamless operation. Once everything is set, we can test our power station by plugging in an air compressor.
Pricing
The cost of building a portable solar power station will vary depending on the components you choose. In this build, we used products from Signature Solar for the battery and Growatt for the inverter. However, there are other options available at different price points that can still provide reliable performance.
Conclusion
Building a 3000W portable solar power station may seem daunting, but with the right components and a basic understanding of electricity, it can be easily accomplished. This portable power station is perfect for providing off-grid and emergency backup power during long-term power outages. While it may require some initial investment, it will bring peace of mind knowing that you have a reliable source of power in case of emergencies.
Don’t let unexpected power outages leave you stranded without electricity. By building a 3000W portable solar power station, you can have peace of mind knowing that you have a reliable source of energy during emergencies. With the right components and a little bit of DIY spirit, you can create your own portable power station that will provide power for years to come.
