This has been my go-to backpacking pillow for over 10 years. I am a side sleeper, so a pillow is required for me to get a good night’s sleep.

Our RV Solar System Upgrade

Sizing an RV Solar System: Part 4

For 10 years our travel trailer’s 280 Watt solar system served us well. We never had a dead battery, even when camping for 30 days in the same spot. Since retirement our camping habits have changed and it was time for some upgrades. This article will look into the options of upgrading (adding on) an existing solar system, along with some of the sand traps and water hazards of the upgrade path.

Sizing An RV Solar System: Part 3

How Much Power Will Your Solar System Actually Harvest?

In Part One and Two of this series we discussed how to measure how much energy is used daily, how to determine needed power storage (what size battery bank), and how to size the solar array.

This post (Part 3) will take a look at all the components and conditions that impact how much solar power will actually be generated. This is the final step to see how the previous calculations will really work for a real world RV solar systems. First we need to define some terms.

New Telescope Remote Power System

Do Lithium (LiFePo4) battery deliver on the manufacturer’s claims. We’ll explore my 30 month experience, which didn’t live up to expectations. But there are some factors that need to be investigated as part of my conclusion. Then I’ll share me new LiFePo4 battery system for my remote telescope kit.

A couple years ago I shared my remote kit  set-up for astrophotography. It included a Lithium (LiFePo4) battery bank consisting of three 16AH lithium batteries wired in parallel. I built this in April of 2021 and was my first experience with LiFePo4 batteries.
