Experience reports from customers
very good quality
As usual from PowerGuen, very good quality. With the included instructions, it's even suitable for beginners. My system consists of a 12.8V 100A battery, a 2000/4000W inverter, and a 420W solar panel. It's an off-grid system. I run a TV, freezer, LED kitchen lights, and Alexa, and occasionally the house water pump and microwave. I find it incredible what this little system can do. hinbekommt.WI would love to try more.

FAQ
Battery accessories are essential to keeping your battery system safe, efficient, and long-lasting. Using the right accessories ensures your batteries are safely installed, properly charged, and protected from overcurrent or short circuits.
A battery monitor monitors the state of charge (SOC), voltage, current, and other important battery data. It provides real-time data on the remaining energy in your battery and allows you to monitor its health. This is especially beneficial for off-grid systems, RVs, marine installations, and other applications where it's critical to prevent unexpected power failure.
Yes, most of our accessories are compatible with LiFePO4, lead-acid, and AGM batteries. However, it's always necessary to check the specifications of each accessory to ensure it's compatible with the voltage, current, and battery type in your system.
Yes, it is recommended to use a dedicated charger that supports the LiFePO4 charging curve. Inappropriate voltage settings on conventional lead-acid battery chargers can result in incomplete charging or battery damage, especially in low-temperature environments. A charger with low-temperature protection should be used.
Not recommended. Ordinary automotive cables may not be able to transmit the high continuous discharge current of lithium batteries. High-quality copper cables that match the rated current should be selected and securely connected with crimp terminals to ensure transmission efficiency and safety.
