Spartan Power Carribean Inverter

Spartan Power Solar

Spartan Power Off-Grid Caribbean Island Inverter with Solar Setup

by Inverters R Us Customer K Frost:

My set-up is a simple solar powered inverter system to supply electricity to my house. I live in a remote area on a Caribbean island, and there is no power available, except what you provide yourself! Over the years, I have gone from no power at all to: power through an extension cord from someone else’s system (and frequent power-outs) to: finally my own system! I purchased a 3300W Spartan Power Pure Sine Wave Inverter from InvertersR Us. Originally, I had ordered another brand in 3000W. But when it was sold out, Inverters R Us substituted the Spartan at no extra cost. I was very thankful and impressed by the customer service, and the inverter has been working like a dream. (I carried it into my country of residence by suitcase!)

My set-up is probably one of the most basic (and affordable) possible: solar panels (6 panels, 176 Watt) , inverter (Spartan 3300W Pure Sine Wave Inverter), charge controller (Outback Flex-Max 60 amp), batteries (8 batteries, Trojan 6V deep-cycle). That’s it (besides wires and circuit panel, of course). No fancy stuff. The electrical wiring in my house is ordinary. I use LED light bulbs to reduce power usage. The biggest pull on my system is the refrigerator (Refrigeration changed my life, people.). I also run an iron on it occasionally, and a water pump. It’s working so well, I may try a small chest freezer!

Really, that’s all I know how to tell you. I’m not very electrically savvy. Someone else told me what I needed and installed the system for me. Poor soul–they tried to explain all the watts, amps, and volts to me more than once or twice. But despite all their efforts, I’m not much more of an electrician. I’m just a happy girl who lives in a house in the middle of nowhere with electricity!


Inverters R Us comment: A very clean, simple setup that works flawlessly for Ms. Frost, she should be able to enjoy her new found power for years to come! To learn more about the inverter in this post, follow that link.


My Spartan Power SP-IC3324 Inverter Charger Setup in Puerto Rico

Spartan Power Inverter Charger SP-IC3324


Jorge’s Spartan Power 3300 Watt SP-IC3324 Setup in Puerto Rico:

Due to the power outages here in Puerto Rico after hurricane María, we are still without power after four months. For this reason I took matters in to my own hands and designed a solar system for my home. I have a 3.3KW @ 24VDC Spartan Inverter SP-IC3324 with two 40A EPEver MPPT Controllers each handling three 260W Mono-crystalline Solar Panels. Supplying the inverter I have a 24VDC Battery bank of approximately 510Ahr.

This inverter has been working like a champ! It’s been a month since I installed it (Have a certified electrician do the installation, there are a few things that can go wrong and ruin your investment) and it works flawlessly. I have my entire home connected to it and it handles it with ease. This inverter handles the refrigerator, all LED lighting a couple of fans and a few electronic chargers with no issues. Also, from time to time my wife uses her hair blower and the washing machine without incidents. Basically we have all our necessities covered with this thing and it continues to perform perfectly. The other day it was rainy and cloudy so the batteries didn’t charge to 100% so I connected it to a gas generator to test the charging capability and it also worked perfect. I ran it for about three hours at 50A and they reached 100% while only consuming about half a gallon of gas. This is a great feature to have in case there is no sun or if used as a back-up.

The case is very rugged and well built. The craftsmanship on this unit is excellent, plus the Spartan logo looks really cool. Customer service reps are very helpful and courteous. Shipping was very fast since it arrived in two days. I am very satisfied with this investment and I would recommend it to anyone looking for a well-built inverter.

Emergency Mobile Power Inverter Setup
Hand Truck Inverter

Customer Uses A 3000 Watt Inverter & Hand Truck for a Mobile Emergency Power Source

This Inverters R Us customer made a pretty sweet mobile emergency power station, check it out and let us know what you think!

Customer: This is an AIMS PWRIG300012120S 3000W pure sine wave inverter mounted on a hand truck supplied by a DEKA Marine master heavy duty deep cycle battery. It has a voltmeter, USB charge port and a 12 volt auxiliary switched port to attach LED lights. The 3000 watt power inverter is designed as a mobile rapid deploy emergency power source for power outages. It can power a sump pump, refrigerator, forced air propane heater or fireplace fan. It is also suitable for powering a computer, modem, base communications and other frequency sensitive equipment that a modified sine wave power inverter may not be suited for.

It is staged with a GFCI cord , various extension cords, a set of jumper cables and a 12 volt 6000k LED light bar for area lighting. The mobile cart can be wheeled to a specific room or setup outdoors with a tarp covering as needed.

Additional things I like about this emergency mobile setup:

  • The hand truck makes the heavy battery easy to move.
  • The added voltmeter indicates battery voltage for remaining power.
  • The whole setup is silent in operation and reliable.
  • The USB port can charge cell phones or power diagnostic equipment.


Inverters R Us Comment: We have seen many mobile emergency power setups before in the past which were usually mounted onto a plastic or steel mobile cart, but never one utilizing a hand truck.  The hand truck certainly makes moving the mobile power inverter setup a bit nimbler while not sacrificing the ease of carrying the heavy battery. We love the additional GFCI outlet, extension cords, light bar and jump cables he added. If you would like more information regarding a setup like this, give one on our expert inverter technicians a call today at 866-419-2616!

How to Choose the Correct Size Power Inverter Battery Cables

Power Inverter Battery Cables

Power inverter battery cables are not some of the most exciting things in the world, but chances are, if you are reading this you probably have an interest in them and may have a question or two in regards to which battery cable is right for your application. First, lets talk about the different sizes of power inverter cables that we carry and which inverters they are rated for. We carry 4 AWG, 1/0 AWG, and 4/0 AWG battery cables that are made in the USA and cut, crimped and heat shrunk here in good ole Reno NV by skilled craftsman that take pride in their work.  Speaking of Reno, here’s a quick pitch to the locals: If you need great quality, UL battery cables made fast, give us a call at 866-419-2616. Order & pickup the same day.

 4 AWG Battery Cables

Four AWG battery cables should be used on power inverters rated up to 1500 watts and most commonly used on 900, 1000, 1100, 1200 watt inverters. Smaller sized inverters generally come with a short 6 AWG cable which is included with the inverter. You can find our 4 AWG cables here on IRU and on Amazon. Most customer’s will use a 150A ANL fuse kit that goes in-line on the positive cable from the power inverter to the battery.


1/0 AWG Battery Cables

1/0 AWG battery cables should be used on power inverters rated up to 3500 watts and most commonly used on 2000, 2200, 2500, 3000, 3300 and 3500 watt inverters.  You can find our 1/0 AWG cables here on IRU and on Amazon. We have 200A and 300A ANL fuses and fuse kits available for use with 1/0 AWG cables.  You can find them on IRU and Amazon as well.

4/0 AWG Battery Cables

4/0 AWG battery cables should be used on power inverters rated over 3500 watts and most commonly used on 4000, 4400, 5000, 6000, 6600, 7000, 8000, 9000, 10,000 and 12,000 watt inverters.  You can find our 4/0 AWG cables here on IRU and on Amazon. For these larger applications, use one of the 500A ANL fuse kits, once again found here on IRU or on Amazon.


In Review:

4 AWG – up to 1500 watts
1/0 AWG – up to 3500 watts
4/0 AWG – over 3500 watts

If you have any questions regarding cables and which size might be right for your application, please don’t hesitate to give us a call at 866-419-2616 and we can walk you through everything you need.
