Solar Inverter Manufacturer — China Factory-Direct (On-Grid, Hybrid, Off-Grid)
On-grid, hybrid and off-grid solar inverters from 3 kW to 100 kW — CE / TÜV / IEC certified, container-ready.
SolarBoltPro supplies CE / TÜV / IEC 62109 certified solar inverters from a single audited factory in Guangdong, sized from 3 kW residential up to 100 kW three-phase commercial. Three sub-systems are stocked for container shipment: on-grid string inverters for commercial rooftops and utility feed-in, hybrid inverters with battery interface for self-consumption and demand-shift, and off-grid inverters hardened for telecom towers, agriculture pumps, and remote sites with poor utility availability.
Every unit ships with a CE Declaration of Conformity and the IEC 62109-1 / 62109-2 test summary. SASO (Saudi Arabia), SONCAP (Nigeria), and SNI (Indonesia) attestations are issued on request before order confirmation. Standard MOQ is 10 units; full-container pricing starts at 60 units (20HQ) or 120 units (40HQ). Lead time for stocked SKUs is 7 working days FOB Shenzhen; custom-firmware orders run 21 working days.

Frequently asked questions
What is the difference between on-grid, hybrid and off-grid solar inverters?
On-grid inverters feed solar power directly into the utility line and shut down when the grid is down (anti-islanding). Hybrid inverters add a battery port, support self-consumption first, and can keep critical loads alive during grid outages. Off-grid inverters work fully independent of utility power, run from battery + PV, and are sized for sites where grid is unstable or absent (telecom BTS, irrigation pumps, mines).What certificates do your solar inverters carry?
Every SKU ships with CE (LVD + EMC) and IEC 62109-1 / 62109-2 test reports. SASO IECEE (Saudi Arabia), SONCAP (Nigeria), SNI (Indonesia), G99 (UK utility) and AS/NZS 4777.2 (Australia / New Zealand) are available on request and issued before order confirmation.What is the typical MOQ and lead time for a container of inverters?
MOQ for sample / pilot orders is 10 units. A 20HQ container holds roughly 60 units of 10 kW class on average; 40HQ ≈ 120 units. Stocked SKUs ship in 7 working days FOB Shenzhen / Ningbo; custom-firmware or country-localized orders take 21 working days.Can you provide the inverter datasheet PDF before I commit?
Yes. Tap "Request Quote" or email w2246802923@gmail.com and our application engineer will share the full datasheet PDF (electrical curves, efficiency at partial load, derating tables, IP rating, dimensions, wiring diagrams) within 24 hours. No NDA required for the public datasheet.Do you offer engineering support sizing the inverter for my project?
Yes. Send the panel model, total kW DC, string layout, and site coordinates. Our engineer returns a sized BOM (inverter model, recommended string count, DC overload ratio, AC breaker, recommended cable cross-section) within 1 working day. The service is free for projects with FOB value above USD 5,000.What is the standard warranty?
All inverters carry a 5-year manufacturer warranty for material and workmanship defects (10 years available as a paid extension). Battery-side electronics on hybrid inverters carry the same 5-year term. RMA is handled through our regional warehouses or by replacement-board courier.
