CHEAP DIY Solar Power Portable Generator

People & Blogs

Introduction

Welcome back to Tara Hill Farm! In this article, we explore a pressing question: Can a DIY solar system serve as an effective replacement for our Honda standby generators that we rely on during power outages?

Understanding the Problem

With inconsistent power from our electricity provider, we installed a transfer switch for easy connection to our Honda generators. These generators provide backup power for critical loads in our home whenever outages occur. Typically, our power cuts last anywhere from five minutes to six hours, happening approximately every three weeks. To enhance our power reliability, we decided to experiment with a cheap DIY solar power system with battery backup.

Our Solar Power Setup

Our goal is to create a solar generator system capable of delivering at least 3,000 watts through our transfer switch, covering ten critical load circuits. Here are the components we assembled:

  1. Inverter Charged Controller: We chose a 3000 watt solar off-grid inverter charger from Signature Solar, which can output 3000 watts and charge from both solar panels and AC from the grid.

  2. Battery: The EG4 Life Power 5.1 kWh lithium-ion battery provides about 4 kilowatts of usable power.

  3. Solar Panels: We found eight used LG solar panels (280 watts each) on Facebook Marketplace at around $ 75 per piece. Together, they provide 2240 watts of solar power.

  4. Hand Cart: We mounted all of our equipment on a sturdy hand cart, making it easy to transport.

  5. Connecting Components: Utilizing provided battery cables and a suitable power plug, we ensured that all parts were easily connectable.

Testing the System

To test the effectiveness of our DIY solar generator, we simulated a power outage by switching off our main breaker. After powering up our battery and inverter, we gradually brought our critical circuits online.

We were pleasantly surprised as the system powered all ten circuits effectively, showing a battery capacity of around 65% while drawing about 600 watts at peak usage. The estimated runtime based on our current load suggested we could run on battery power for about 6 to 7 hours.

Cost Comparison

A critical part of our challenge was to determine if we could assemble this solar system for less money than purchasing an all-in-one solar generator. Comparing our DIY build, costing around $ 2400 (excluding solar panels), to brands like EcoFlow Delta Pro ($ 3600) and Blue Eddy EP 500 Pro ($ 5400), it was clear that we had created a more economical solution.

Benefits of the DIY System

Our DIY system, affectionately named the "Cheapo Flow 3000," has several advantages:

  • Cost Efficiency: Significantly cheaper than branded systems.
  • Scalability: Capable of taking in up to 5,000 watts of solar power.
  • Ease of Repair: Individual components mean easier access for repairs.

While building this system requires some electrical knowledge, it's a viable option that can help those struggling with unreliable grid power. We'll always encourage consulting with an electrician if you're uncertain about any technical aspect.

We hope you found this exploration helpful! At Tara Hill Farm, we are continually testing alternatives for power reliability.
