FIMER PVS-100/120-TL

Commercial PV inverter

FIMER documents SunSpec Modbus RTU and TCP for PVS-100/120-TL. Use the exact rating and wiring-box suffix because AC voltage, MPPT count and string monitoring differ. This guide is read-only. Plant control, protection and grid settings stay with the commissioned system.

Compatibility

Compatible through documented SunSpec Modbus

The exact-family product manual documents SunSpec-compliant Modbus RTU and TCP, and FIMER publishes a PICS workbook for the PVS-100/120-TL.

PVS-100-TL and PVS-120-TL only, with the full model suffix, firmware and commissioned interface recorded. Read monitoring data only. Do not change active-power, reactive-power, protection or grid settings.

Specifications

PVS-100-TL is rated 100 kW at 400 Vac and PVS-120-TL is rated 120 kW at 480 Vac. The product family has two- and six-MPPT wiring-box variants, so the family name alone is insufficient for array or point design.13

Interface

Documented measurements and integration boundaries for PVS-100/120-TL.

  • Inverter identity and firmware from the implemented SunSpec common model.
  • AC power, voltage, current, frequency and energy where returned by the installed SunSpec model set.
  • DC power and operating state where the installed variant and firmware expose them.

Assessment

Exact PVS-100/120-TL suffix and firmware, using documented SunSpec Modbus only.

InteroperabilitySupported with conditions
Exact-family SunSpec RTU and TCP plus a PICS are published; model and firmware discovery remain required.12
AccuracySupported with conditions
Electrical measurements and identity models are documented, while available points depend on the installed suffix and firmware.12
SecurityLimited
The local Modbus paths do not provide transport encryption or peer authentication, so network isolation and read-only enforcement are required.1
ReliabilitySupported with conditions
Environmental limits and communications hardware are published; polling recovery and coexistence need site testing.13
RuggednessSupported with conditions
IP66 and installation limits are published for the family, subject to the exact variant and installation method.3
ScalabilitySupported with conditions
Ethernet daisy-chain and addressed serial operation are documented, but client roles and segment loading need an engineered site plan.1
LifecycleSupported with conditions
FIMER publishes an exact-family manual, datasheet and PICS with revisions; deployed firmware and retained configuration still need recording.123

Setup

  1. Identify the exact inverter

    Record PVS-100 or PVS-120, the complete wiring-box suffix, serial number and firmware. Confirm the site AC voltage and MPPT count against the nameplate.

  2. Preserve plant control

    Record the existing logger, plant controller and grid settings. Use a read-only client and do not enable or exercise power-control functions.

  3. Choose one documented interface

    For TCP, use a permitted protected LAN endpoint. For RTU, confirm slave mode, address, serial framing and termination without displacing the current bus master.

  4. Discover before decoding

    Read the SunSpec signature and model headers, then use only models listed by the inverter and applicable to its firmware. Do not paste offsets from another ABB or FIMER family.

  5. Validate measurements

    Compare identity, operating state and one live power value with the inverter display or commissioned monitoring system before expanding the point list.

Common questions

Does every PVS-100/120-TL have six MPPTs?
No. FIMER publishes both two- and six-MPPT wiring-box variants. The complete suffix determines the input topology.13
Does this guide permit inverter control?
No. It covers read-only SunSpec monitoring. Active and reactive power commands, protection and grid settings remain outside this integration.1
Can an RS-485 connector alone justify an Edge path?
No. The path here is supported by the exact-family manual and PICS, and still requires the commissioned slave settings and an available bus role.12
