Frequently Asked Questions
Common questions about the all-in-one home energy storage system
What is the difference between the PT5510S and the PT5515SP / PT5516SP?+
Both deliver 5500W output with a built-in single MPPT. The PT5510S has a 10.24kWh battery (200Ah cells), while the PT5515SP / PT5516SP offer 14.336kWh or 16.0768kWh (280Ah or 314Ah cells) for longer backup time in a larger cabinet.
Can I expand the battery or power later?+
Most models support parallel expansion of both power and battery capacity (customizable). The PT3570S / PT3580S support parallel battery expansion. Tell us your target capacity and we will confirm the configuration.
What AC voltage do these systems output?+
All models output 230Vac at 50/60Hz. Please tell us your destination country so we can confirm grid-connection and certification requirements.
Can I get certification documents?+
Please contact us with the model and destination market, and we will provide the applicable certification documents on request.
Is OEM / private-label branding available?+
Yes. Private-label branding and custom configurations are available with flexible MOQ. Contact us via WhatsApp for OEM pricing.
Is the system suitable for outdoor installation?+
The protection degree is IP20 — indoor installation only (garage, utility room, living space).
