CLEAR ANSWERS

Frequently Asked Questions

Discuss your project ↗
What is the difference between a PCS and a hybrid inverter?

A power conversion system (PCS) provides bidirectional conversion between a battery DC bus and the AC system. A hybrid inverter adds PV conversion and may also integrate MPPT, grid/off-grid transfer and EMS functions; the correct choice depends on the project topology.

Which VGRID product provides a wall-mounted 135 kW microgrid PCS?

LEONA-H135K is a split-architecture IP65 wall-mounted microgrid PCS. The supplied brochure lists 135 kVA rated off-grid output; confirm the active kW rating against the approved datasheet.

What is the LEONA-M200K 200 kW wall-mounted PV DC/DC controller used for?

LEONA-M200K is a PV-side MPPT controller for DC-coupled solar-storage systems. The brochure lists 8 MPPT channels, 16 PV inputs and a 200–950 V MPPT range; it is not a battery PCS or hybrid inverter.

What is integrated in the SP250HAG2T 250 kW hybrid inverter cabinet?

The SP250HAG2T combines PCS, MPPT, EMS, grid/off-grid transfer and AC/DC distribution in one cabinet, with a built-in isolation transformer. It can connect PV, batteries, the utility grid and a diesel generator.

How does LEONA-B750K differ from SP375/500HAG2?

SP375/500HAG2 integrates PV MPPT in the cabinet. LEONA-B750K is a split-type, grid-forming hybrid system with separate optional MPPT controllers, EMS and an isolation transformer; its brochure includes DC/AC-coupled, 2.25 MW parallel and UPS designs.

Can VGRID PCS and hybrid inverters be paralleled for 1 MW, 1.5 MW or 2 MW systems?

Models approved for parallel operation can be combined into megawatt-class solutions, including 1 MW, 1.5 MW and 2 MW design targets. The final quantity and cabinet combination must be checked against grid voltage, battery voltage, PV input, transformer, protection and EMS requirements.

Do these systems support grid-connected, off-grid and diesel-generator operation?

Selected PCS and hybrid inverter models support grid-connected and off-grid modes, generator coordination and grid/off-grid transfer. Transfer time and the required switching equipment vary by model and system design.

Should a solar-storage project use AC coupling or DC coupling?

AC coupling is often suitable for retrofits or systems with independent PV and battery conversion paths. DC coupling can share a DC bus and use PV DC/DC conversion; the decision should follow the PV voltage, battery range, operating modes and existing equipment.

What information is needed to select a PCS or hybrid inverter?

Provide the project country, grid voltage and frequency, required AC power, battery voltage and capacity, PV array data, grid/off-grid or generator requirements, and preferably a single-line diagram and load profile.

Can VGRID provide OEM, ODM or project-specific cabinet configurations?

OEM, ODM and cabinet integration can be reviewed for qualified projects. Send the target power, electrical architecture, enclosure requirements, applicable standards and drawings so the engineering team can confirm feasibility.

PROJECT ENQUIRY

Have a one-line diagram?

Send the target power, country, grid voltage and PV or battery details. We will use them to discuss the right equipment.
