Transformer sa Pagtumong sa Pag-imbak sa Enerhiya ng Photovoltaic

Pangutana sa Produkto：

Ang grid-connected energy storage auxiliary isolation transformer para sa photovoltaic power generation gamiton sa pangkalahatan para sa solar inversion, may kasama nga mga karaniwang voltages sama sa 800V hangtod 400V, 380V, 690V hangtod 400V, 540V hangtod 400V, etc. (mao kini customizable depende sa gipangangailangan); tungod sa lawas nga photoelectric efficiency sa photovoltaic silicon panels, ang transformer nimo mahimong ma-require og dako nga efficiency. Ang photovoltaic isolation transformer gisuloban og microcomputer intelligent time controller aron masugdan ang pag-operate sa adlaw ug pag-stop sa gabii aron mapalit ug wala mao ang no-load power loss, usa ka temperature controller aron real-time monitoron ang operating temperature sa transformer, kontrolhon ang pagsugod ug pag-stop sa cooling fan, ug automatic stop ug disconnect sa transformer kung ang operating temperature maoa asa sa taas pa sa set critical temperature alang sa proteksyon sa safety sa transformer body, usa ka self-reset overvoltage ug undervoltage protector aron maprotektahan ang islanding operation, usa ka surge protector aron makaprotect sa lightning damage sa equipment ug mapataas ang safety factor sa power generation system, ug usa ka knife switch sa grid-connected side aron mapadali ang effective operation ug maintenance sa equipment.

Punong Katangian:

• Smart Controls: Microcomputer time controller nagreduce sa nighttime no-load losses.

• Safety Protections:

• Temperature monitor kon ang auto-shutdown sa critical thresholds.

• Over/under-voltage self-reset protector prevents islanding.

• Surge arrester for lightning protection.

• Grid-side knife switch for maintenance.

• Flexible Configurations: Available in single/multi-unit combinations (1:2, 1:3, etc.) for scalable PV systems.
