A game-changer for my solar system. The battery integrates flawlessly with my inverter via the RS485 communication.
Antonio Santos –
The 5-year warranty shows the manufacturer’s confidence. It’s a solid investment for my home’s backup power.I’ve roughly calculated that by the third year of using this system, the cost of the equipment has already been covered by the electricity savings. From the fourth year onward, the system allows me to essentially get free electricity!
Carlos –
Nasa labas ng sentro ng Maynila ang aking pactorya, at dati ay laging problemado sa mga pagkawala ng kuryente. Tuwing nagkakaroon ng brownout, kailangan naming itigil ang produksyon, na nagdudulot sa akin ng malaking kawalan sa kita. Noong 2024, nag-install ako ng sistema ng imbakan ng enerhiya mula sa alltopelec, at tuluyan nang nawala ang problema sa brownout. Ngayon, tuluy-tuloy at matatag na ang operasyon at produksyon ng aking pabrika. Para sa akin, ito ay isang napakagandang pamumuhunan.

Safety first! Knowing it uses CATL’s automotive-grade LiFePO4 cells gives me so much peace of mind. No risk of fire.

good
Vicente Castillo –
Much quieter and cooler operation than I expected. No noisy cooling fans, just silent and reliable power.Since installing this solar energy storage system, I now only pay 10% of my previous electricity bill each month.
