FAQ
Sizing starts with daily energy consumption, maximum load power, required backup days and local sunlight conditions. Load surge current, installation environment, battery type and budget should also be reviewed.
Gel or lead-acid batteries are common for stable and cost-sensitive backup systems. Lithium batteries are better when higher cycle life, lighter weight and higher usable depth of discharge are required.
Yes. The page is designed for B2B inquiries covering solar panels, storage batteries, inverters, MPPT controllers and off-grid system matching.
Provide the load list and quantity, rated and surge power, daily runtime, backup target, project location, installation environment, output voltage and expected order quantity.
Continuous inverter power must cover simultaneous loads, while surge capability must cover motors, pumps and compressors. Battery voltage and PV input limits must also match.
Not from nominal capacity alone. Usable depth of discharge, inverter efficiency, temperature, ageing, load variation and simultaneous PV charging all affect runtime.
Some models support common communication protocols, but compatibility must be confirmed against the BMS, inverter protocol version, port and firmware rather than voltage alone.
No. Price, certification, availability, lead time, warranty and trade terms must be confirmed for the exact model, quantity, destination and project requirement in a formal quotation.
Send load power, daily energy use, backup time, country or region and installation scene so we can prepare the first configuration direction.
