Feeling puzzled about why your solar batteries are constantly meeting their demise? I’m an electrical engineer who’s practically held post-mortems for countless DIY solar projects gone away, and one glaring culprit stands out: improper charge controller sizing. Whether it’s residential solar or heavy-duty industrial setups, after years of consulting, I can attest that nailing the…
With over a decade designing solar installations, I’m intimately familiar with the intricate dance between panels, wires, and the unsung heroes allowing it all to operate safely: fuses. But while most users recognize traditional “small appliance” fuses, they’re often confused regarding the specific differences between two more heavy-duty varieties prevalent in PV systems – midi…
Installing a solar photovoltaic (PV) system is a great way to utilize renewable energy while reducing your electricity bills. But the high upfront cost of batteries for energy storage makes some homeowners wonder – can I use my solar panels without batteries? The short answer is yes – with the right equipment, you can use…
With home solar system installations accelerating globally, solar-paired home battery backup is a fast-growing trend for added resilience and maximizing solar self-consumption. However, amid the excitement over emerging battery technologies, questions linger about real-world lifespan expectations. On average, today’s solar batteries operate reliably for 5-15 years based on chemistry and use factors before needing replacement….
Having issues getting your Renogy charge controller to charge your battery? This frustrating problem can keep your solar power system from operating properly. But don’t worry – with some troubleshooting and testing, you can likely identify the root cause and get your charge controller back to charging your batteries fully again.

As more people adopt solar power systems for their homes, a common question arises – is it possible to charge AGM batteries with solar panels? Absorbed Glass Mat (AGM) batteries are a popular choice for solar energy storage due to their deep cycle capability, low maintenance requirements, and resistance to vibration. However, they require a…
Victron Energy’s BlueSolar MPPT 75/15 controller is a popular 15A solar charge controller for small to medium off-grid solar power systems. However, many user have reported that they have connected their solar array and batteries properly but the unit fails to charge. So, Why Your BlueSolar MPPT 75/15 Won’t Charge? The heart of the matter…
Charging absorbent glass mat (AGM) batteries with maximum power point tracking (MPPT) solar charge controllers is an increasingly popular strategy for keeping batteries optimized in renewable energy systems. However, AGM batteries have different charging needs than flooded lead-acid batteries. In short, you can charge your AGM batteries with an MPPT charge controller without any issues….
For solar-powered homes, extended periods of cloudy weather can make it challenging for solar panels to fully charge your battery bank. In such cases, you can use a gas-powered generator as a backup power source to charge your batteries when needed. But do you know how to use a generator to charge solar batteries? To…
Battery storage in your solar energy system allows you to retain power overnight or during grid outages. But properly sizing the battery bank capacity is crucial to meet your household’s energy needs. But do you know how many batteries are needed for a 1000-watt solar system? For a 1,000 watt solar system, the number of…
