| What Error 04 Means on Your Solar Inverter – Insight from Sona Solar’s David Manema |
Among the most common inverter issues reported by solar users is Error 04. While it may sound intimidating, this error is both preventable and manageable with the right knowledge and guidance. In this article, David Manema breaks down what Error 04 really means, what causes it, how to fix it, and, more importantly, how to prevent it from recurring.
What is Error 04?
Error 04 is a battery voltage error that most commonly occurs when your solar inverter detects that the battery voltage has dropped below the safe operating range. When the voltage dips too low, the inverter shuts down power output to protect the battery from deep discharge damage. This type of automatic shutdown is a built-in safety mechanism. However, frequent occurrences of this error can signal deeper issues in your solar setup or usage habits. Understanding why this happens is key to maintaining a healthy, long-lasting solar system. According to David Manema, many clients initially panic when they see Error 04, believing their entire solar system has failed. In reality, it’s often a manageable situation that just requires informed intervention.
Another significant cause is the natural degradation of batteries. Over time, all batteries lose their ability to hold a full charge. If your battery is old, damaged, or poorly maintained, it may no longer provide the expected voltage levels, leading to frequent low-voltage warnings. David explains that in many cases he’s seen, clients continue to use batteries well past their optimal lifespan, which increases the chances of encountering this error.
Improper system sizing also plays a big role. If your solar system, particularly the battery bank and solar panels, was not sized correctly to match your energy needs, then it may struggle to keep up with your household's power demands. This mismatch results in chronic undercharging and eventual over-discharge.
If the issue persists, it’s important to test the battery voltage using a voltmeter. This will help determine whether the battery is still within the safe operating range. If the voltage remains extremely low, this may indicate that the battery is damaged and needs to be replaced.
Another step David advises is to thoroughly inspect all wiring connections between the inverter, battery, and panels. Make sure every terminal is tightly secured, clean, and free of corrosion. This alone can sometimes resolve voltage errors without any hardware replacement.
In certain inverter models, a manual reset is required after resolving the issue. This usually involves switching off the inverter, waiting a few minutes, and turning it back on. If you're unsure how to do this correctly, the safest route is to consult with a certified technician.
David Manema and the Sona Solar Zimbabwe team are always ready to assist in these cases. Whether it’s a site visit or a quick call for remote troubleshooting, help is never far away.
Energy management is another essential habit. Avoid running high-wattage appliances at night or during cloudy days. This includes items like kettles, irons, electric stoves, and geysers. If your battery isn’t fully charged, these appliances can quickly drain power and trigger low voltage errors.
Routine maintenance can also go a long way. Have your system checked at least every six months by a professional technician. A routine inspection will include testing battery health, checking inverter settings, and verifying that all connections are intact. Catching small issues early can prevent expensive damage and avoid error messages like Error 04.
Lastly, system upgrades should be considered if your energy needs have increased. If you’ve added more appliances or your household size has grown, your original system may no longer be sufficient. David recommends having your system re-evaluated to ensure it still meets your current energy usage.
You can call or WhatsApp directly on 0781190001. Whether you’re looking for advice, repair services, or a full system upgrade, David and the Sona Solar team are here to help.
Don’t let a small error disrupt your solar lifestyle. With expert guidance and proper system care, you can enjoy clean, reliable energy every day - without interruptions.

What Causes Error 04?
There are several factors that can trigger Error 04, and they often relate to how the solar system is being used or maintained. One of the most common causes is battery over-discharge. This happens when you draw too much power from the battery, especially during periods when solar generation is low, such as during cloudy weather or overnight. If your solar panels haven't had sufficient sunlight to recharge the batteries during the day, any continued use of electricity at night can drain the battery beyond its minimum voltage.Another significant cause is the natural degradation of batteries. Over time, all batteries lose their ability to hold a full charge. If your battery is old, damaged, or poorly maintained, it may no longer provide the expected voltage levels, leading to frequent low-voltage warnings.

This mismatch results in chronic undercharging and eventual over-discharge.
How to Resolve Error 04
The good news is that Error 04 can be resolved, often without needing to replace your entire system. The first step is to allow the battery to recharge. If it’s during the day, let your solar panels charge the battery without any load drawing power from it. Switch off all appliances for a few hours and monitor whether the error clears once the voltage stabilizes.If the issue persists, it’s important to test the battery voltage using a voltmeter. This will help determine whether the battery is still within the safe operating range. If the voltage remains extremely low, this may indicate that the battery is damaged and needs to be replaced.

Preventing Error 04 from Recurring
Preventing Error 04 is about more than just fixing the current problem. It involves a proactive approach to system care and usage. One of the most important steps is ensuring that your system receives adequate charging. Your solar panels must be clean, well-positioned, and properly angled to capture as much sunlight as possible. Dust, bird droppings, and shading from trees can all significantly reduce panel output, leaving your battery undercharged and vulnerable to over-discharge.Energy management is another essential habit. Avoid running high-wattage appliances at night or during cloudy days. This includes items like kettles, irons, electric stoves, and geysers.
