Common Pitfalls When Purchasing Powerwall Batteries
Most Powerwall Battery problems come from choosing the wrong supplier—not the wrong chemistry. Here are five issues Saftec helps buyers avoid:
Inverter mismatch – Many low-cost models support only RS485. Saftec provides full RS485 / RS232 / CAN communication for stable inverter pairing.
Unverified safety – Products lacking UN38.3 / IEC62133 cause shipping or installation failures. Saftec delivers globally certified batteries.
Overrated capacity – Some 25.6 V units are marketed
Difficult installation –
Short lifespan claims – Low-grade cells fade after 500 cycles; Saftec uses EV-grade LiFePO₄ rated for 6,000 cycles.
