Victron Color Control Gx Settings
For now were really just looking to see the Color Control GX has turned on. Remember, the inverter itself should be shut off and the 200A Pole Toggle should also be shut off.
Depending on your setup, you will need to make some adjustments to the settings for the Color Control GX.
- Settings > System Setup > DVCC
If youve connected everything properly you should see your batterys percentage, voltage, amperage, and wattage all on the battery portion of the screen.
Keep in mind that most systems will treat the battery pack as 50% full by default until its been charged to 100%. So if it is showing a lower percentage than what you think it should be, just be patient.
Now you can test the Inverter. Turn on your 200A Pole Toggle , and then flip the power button on the Quattro. The green light should turn on, and the Inverter icon on the Color Control GX screen should change add a green light, and change the status to Inverting.

Freezer Solar Panel Requirements
To be clear, this guide is for freezers only, and does not include refrigerators with freezers. We have a separate guide if you want to run a refrigerator on solar power. While there are all kinds of freezers, it is possible to use the following guidelines and determine how much solar power you will need
The formula is: find the freezer power consumption in watts and add 20%. The result is the minimum solar panel size you should use. The following chart shows the most common freezer sizes, their power consumption and the minimum solar panels required.
| Freezer Size | ||
|---|---|---|
| 18 to 22 cu ft. | 350W 500W | 600W |
Solar panel power output should be rounded off to the nearest size available. If a 9 cu. ft. freezer requires 144 watts of solar power, get a 150W PV module. We recommend the Newpowa 160W solar panel as it is made of high quality monocrystalline and can be used in homes, RVs and boats.
If your 15 cu. ft. freezer needs 528 watts, two 275W or 300W solar panels will do. A good choice would be the Huajin 300W flexible solar panel as it has a high efficiency rating and works in different environments.
As you may have noticed the power consumption varies quite a bit. That is because freezers come in a wide range of sizes, shapes and designs. Some models are also more energy efficient than others.
Freezer power consumption is affected by several factors, so under certain conditions a freezer may consume power than what you might expect. This is particularly true if the freezer is full.

Can I install my own solar panels?
You can install your own solar panels to save on labor and design costs. However, there are a few disadvantages to consider: Professional solar companies have access to wholesale prices of a wider range of solar equipment, and improper installation can lead to severe safety concerns or inefficient systems.
Is it illegal to install your own solar panels?
It is not typically illegal to install your own solar panels, but this will depend on your area. You should always check with your local zoning board to ensure that youre even permitted to do a DIY solar installation, especially if youre planning a completely off-grid system. If you plan to feed excess energy back to the central power grid, youll need to apply for interconnection with your local utility company.
Is it cheaper to install your own solar panels?
It can be cheaper to install your own solar panels, as youll save money on upfront costs like labor, design, transportation and more. However, by purchasing your panels online or directly from a distributor, you may not have access to the best solar panels or as wide a product selection as you might like.
How To Build A Diy Solar Battery Storage
Calculate Your Load and Select Your Batteries:
Now that you know what you will need, you can actually assemble and install your DIY solar battery storage. The first step is calculating the amount of electricity you will need to store. By calculating your load, you will be able to figure out how many batteries your storage system will require.
Use our Solar Watt Hour Load Calculator to determine your storage needs. From there, select the number and type of batteries you will need to satisfy your load requirements.
You will be able to find exactly what you need by browsing our Deep Cycle Solar Battery Collection, which contains 12V, 24V, and 48V solar batteries from some of the most reputable brands in the industry

Sizing A Hybrid Solar System
Remember, as previously discussed a hybrid solar system relies on both the utility grid in conjunction with its own battery bank.
The sizing of a hybrid solar system in terms of the panels needed is exactly the same as the sizing of a grid-tied system, so please follow the same steps.
Here you want to focus on the sizing of your battery bank.
Sizing your battery bank
Unlike off-grid solar systems, hybrid solar systems simply need to cover your essential loads with the battery bank.
In order to correctly size your battery bank, you have to collect and list the consuming load of all your essential household appliances.
Here is an example list we created of essential loads we would like powered in the event of a power outage:
| Loads |
|---|
| 480 |
| 6090 Watt Hours |
No battery bank is 100% efficient, for this reason, you need to account for a 15% battery loss.
Therefore, you need to divide your total wattage by 0.85 battery efficiency:
6090Wh/85% = 7164Wh total battery capacity required.
Batteries are not rated in watt-hours, so it is best that you convert this into amp hours.
To do this simply divide the batteries capacity by the battery voltage rating
In this example, we are using 12V batteries.
Therefore, 7164Wh/12V = 597 Amp hours .
In order to know how many batteries you will require, just divide your total Amp-hours by the battery Ah.
597Ah/100 = 5.97 round this off to 6. You will need six 100Ah batteries to supply enough power to the essential items mentioned in the table above.
Pros And Cons Of Diy Solar Panels
DIY solar panel installation allows you to save more than having a professional do it for you.
Solar kits have become more affordable than a pro service, which can cost at least $7 per watt. Therefore, a 5kW system is around $35,000 before incentives. Installing on your own means you do not have to pay for the installation expenses, giving you about $4-per-watt or a total of $15,000 worth of savings for a 5kW system.
Making a DIY solar power system becomes easier every year. There are tons of solar kits online or at a local hardware store to help you get started. You can get a complete home solar array and start installing it. With a professional installer, you may be required to wait several weeks so the company will get the equipment and give you the schedule of the installation.
Net solar metering is also a benefit in which this solar incentive lets you store energy and send the excess to the grid. Many companies will repay you for the electricity you produce.

Do You Need A Battery To Run Freezers On Solar Power
Almost everyone who runs freezers on solar panels use a battery, because without it you will not be able to use the freezer when the sun goes down.
A 50ah battery can run a 3 cu. ft. freezer for about 3 hours. To run a 5 cu. ft. freezer for 24 hours, a 150 watt solar panel and a 400ah battery are required. You can use one 400ah battery or several smaller batteries like five 80ah for instance.
In this scenario, our 5 cu. ft. freezer uses 120 watts an hour.
120 watts x 24 = 2880 watts
A 150 watt solar panel can produce 750 watts in an hour.
That means you need another 2130 watts, which a 400ah 12V battery bank can supply. 400ah is actually 4800 watts, but only half 2400 watts is usable per charge on lead acid batteries.
This solar panel and battery combo produces more power than what our 5 cu. ft. needs. But in many instances, the panel and battery may not reach 3150 watts, which is why we have added a safety margin.
Solar panel cells are sensitive to shading, and even a few leaves blocking the panel can slow production significantly. A cloud that suddenly blocks the sun has the same effect. So make sure the sky is clear when you set up a solar panel.
