FAQ for this category
Do you supply electrical components for BESS and substations?
Yes: circuit breakers and contactors (e.g. ABB S803PV-S20 for DC circuits), PLC controllers and I/O modules (Siemens SIMATIC S7-1200), sensors and meters. For projects we build a full BOM from your single-line diagram.
Where to check parts compatibility with inverters?
The open compatibility table at apex-export.com/compatibility/: inverter ⇄ part cross-reference with search. Boards are on request. The table grows as new pairs are verified.
What warranty do parts carry?
Genuine items carry the manufacturer's warranty terms. Certified analogues carry the supply-contract terms. Warranty conditions are fixed in the invoice for every line item.
Do IGBT modules need certification?
It depends on the intended use and power class of the equipment they go into. We avoid a one-size-fits-all answer: requirements for your specific item are confirmed on request against the current regulatory base.
Do analogues carry TÜV certificates?
Yes, analogues ship with valid TÜV / gPV certificates; certificate copies are provided together with the quote.
How to certify parts in Kazakhstan?
Kazakhstan is in the EAEU — the rules differ from Uzbekistan's. Key differences and procedures are covered in our import guide (apex-export.com/guides/import-uz/, Kazakhstan section). For a specific item, requirements are confirmed on request.
