I would try to do this before the sun was hitting my solar panels for a true reading of the actual battery voltage. My Electrical Life Pre-Battery Monitorīefore I had my battery monitor, my daily routine would go something like this: I would wake up in the morning and cycle my solar charge controller’s display through to the screen showing the battery voltage. Now, with VictronConnect, I can see how much power is being placed into my batteries from my solar system, how many amp-hours of power I’ve used, and when my batteries have been topped off. I’m even a bit weird about how much I enjoy seeing what’s going on with my batteries. This has turned out to be one of my most-used apps. With the optional Bluetooth Smart dongle (you can purchase the BMV-712 Battery Monitor to get built-in Bluetooth) I can monitor the battery condition via an app on my iPhone. It wasn’t until I installed a Victron BMV-700 Battery Monitor did I finally have an ‘ah-ha’ moment regarding what was going on with my batteries. No clue of the actual flow of electricity in/out of my batteries. I was able to see battery voltage, and that was it. Other than the solar controller’s basic display, there was no way of knowing what was really going on with my batteries. The main headline image in this blog shows that too, plus rigid panel rooftop solar.īack in the early days, I had a couple hundred watts of solar power charging my batteries. Fortunately, the Victron battery monitors are compatible with all system types.Portable solar panel. A good battery monitor must have a shunt.Ĭompatibility: Make sure the battery monitor you choose is compatible with your battery bank and solar system. However, there are a few things to keep in mind when selecting a battery monitor:Īccuracy: Look for a battery monitor that accurately reads your battery’s voltage, current, and state of charge. Section 3: Choosing the Right Battery MonitorĬhoosing the right battery monitor for your off-grid solar system can be daunting. This can reduce the need for costly battery replacements and repairs, saving you money in the long run. By monitoring your energy usage and battery health, you can optimize your energy usage and extend the lifespan of your battery bank. For instance, if your battery monitor shows that it is not holding a charge, you can investigate the issue and fix it before it is permanently damaged.įinally, a battery monitor can help you save money. Moreover, a battery monitor can help you detect problems with your solar system before they become serious. For example, if your battery is low, you can turn off non-essential appliances to conserve power until your solar panels can recharge your battery. You can adjust your energy usage accordingly by knowing how much energy your battery bank has. One of the main reasons a battery monitor is essential in an off-grid solar system is that it allows you to manage your energy usage more efficiently. Section 2: Why is a Battery Monitor Important? This can help prevent damage to your battery and extend its lifespan. This allows you to balance your energy usage and prevent overloading your battery bank.įinally, a good battery monitor can alert you if your battery is overcharged or undercharged. Note: If your battery monitor does not have a shunt, it is not a good battery monitor.įurthermore, a battery monitor can also provide information on how much energy your solar panels produce and how much power your home consumes. A battery monitor typically consists of a shunt installed between the battery bank and load and a display unit that shows the battery’s voltage, current, and state of charge. It gives you real-time information about your battery’s health and performance, allowing you to make informed decisions about your energy usage. Section 1: What is a Battery Monitor?Ī battery monitor is an electronic device that measures your battery bank's voltage, current, and state of charge. This blog post will discuss the importance of a battery monitor in an off-grid solar system and how it can improve your quality of life. However, how can you know how much energy your panels produce and how much energy is available in your battery bank at any time, day or night? This is where a coulomb counting battery monitor is essential. You have everything you need to survive- food, water, shelter, and an off-grid solar system that powers everything in your home. Imagine living off the grid in a secluded cabin surrounded by nature.
