Build Your Own Low-Budget Solar Power SystemThis book is designed to address the concerns of those whose only desire is to build a simple, small scale solar energy system but don't know where to start (or end!). We've been living off the grid for well over ten years now and the most common inquiry we get is from people who want to set up a small solar energy system to power a cabin or camper, or to keep a refrigerator and a few lights on if the grid goes down.

This book is designed to address the concerns of those whose only desire is to build a simple, small-scale solar energy system but don't know where to start (or end!). We've been living off the grid for well over ten years now and the most common inquiry we get is from people who want to set up a small solar energy system to power a cabin or camper, or to keep a refrigerator and a few lights on if the grid goes down. Some have already tried and ended up with woefully inadequate systems lacking the power and balance needed for off-grid life. But there's more to off-grid living than watts, volts and amps. It's important to understand how a solar power system works and how to size it properly for the job you want it to do. In this book I've condensed all the information you need to design your own simple, off-grid, solar power system. I'm not going to teach how to build your own solar panels but I'll tell you how purchase factory components to build the system that fits your needs the best and hopefully save you a lot of frustration and cash while putting it together. We'll see how to understand watts, volts, amps, and ohms and how they apply to deciding how many solar panels you need, the watt ratings you'll have to have for your inverter and charge controller and even how many batteries you'll need for your battery bank. You'll learn about resistance, and how it affects your solar power system. I will explain with diagrams and text the differences between sine wave, modified sine wave and pure sine wave inverters and how that applies to you. I'll explain charge controllers and the reasons for and against PWM vs. MPPT vs. single-stage vs. multiple-stage controllers and which is best for you. I'll tell you a little secret about "efficient" vs. "less efficient" solar panels that will keep you from wasting money on something that's a relatively minor issue. Even if you don't want a "whole house" system you'll learn how to put together balanced small-scale power systems at whatever size you can afford. We'll also look at solar power "kits" and I'll show you how to put together your own that outperform commercially available kits and get more power for less money. My goal here is to simplify that which has been made complicated. I want you to be able to pursue your dream of independence from the grid without spending enough money to break the bank. It can be done, and for less than you may imagine!Shipping Notes

Good sturdy balls
Size: Medium (2.5"), Style: Fetch Pack 2
My dogs love balls! Unfortunately, they tend to chew them up very quickly. My Belgium Malinois chews on this all the time, and it has held up pretty well. Good option for chewers

Fetch Perfection
Size: Medium (2.5"), Style: Fetch Pack 2
If you’re anything like me, fetch is the ultimate game with your furry companion. The Chuckit! Dog Fetch Ball Medley has taken our playtime to the next level with its variety and durability. This 3-pack of medium-sized, ultra-rugged balls is perfect for endless games of fetch without worrying about wear and tear.
I love how each ball has a unique texture and color, keeping my dog engaged and excited every time. The medium size is just right for energetic dogs, allowing for long throws and big leaps. Plus, the rugged design means these balls can withstand even the most enthusiastic chewers and rough play sessions, making them a great investment for active pets.
However, the vibrant colors can sometimes make them easy to lose in green grass or sandy beaches, but a good game of hide-and-seek with your dog is a small price to pay for such fantastic fetch balls. Additionally, while they’re durable, no ball is completely indestructible, so occasional replacements might be necessary for the most aggressive players.
Overall, the Chuckit! Dog Fetch Ball Medley is a must-have for any dog owner looking to enhance their playtime. They’re fun, durable, and keep both you and your dog entertained for hours. A solid 5-star rating for their quality and variety, with a tiny star lost to their occasionally elusive colors.

great ball!
Size: Medium (2.5"), Style: Fetch Pack 2
My pitbull LOVES these. She is a power chewer and tough on balls and toys and tends to go through them insanely quick. She is still on her first ball out of this pack and its been at least two months. It is a little small for her mouth but she doesn’t seem to mind, as it has quickly become one of her favorites. Not a loud ball and it doesn’t usually make that wet chewy noise when shes going to town on it which is huge for me😂😂 Safe for my pittie so i’d imagine a smaller dog would be just fine.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.
