Techfine PA30210 30 A MPPT controller: Verify PV, Battery and Load Configuration

Name: Techfine PA30210 30 A MPPT controller: Verify PV, Battery and Load Configuration
Brand: Techfine

This page organizes the current local source record for a Techfine PA30210 30 A MPPT controller. It preserves the displayed current, voltage and PV-input wording without converting a shared family table into a universal installation claim. The displayed values belong to a controller family or selected member. Confirm the exact model suffix, nameplate, current revision and destination version before fixing an order specification. Use the final RFQ to connect the exact controller to the PV string, battery chemistry/profile, DC load and site protection design.

Current document status

The current record has an embedded technical table but no verified model-specific installation pack in this review. Request the current datasheet, manual, wiring diagram, model suffix/nameplate, battery settings and destination compliance evidence before order release.

Current table evidence

Read the exact controller member before sizing a PV string

PV Voc, operating window, nominal battery voltage, current and rated PV watts must stay tied to the same table cell and the coldest site condition.

Displayed controller identity

PA30210 30 A MPPT controller is the current route identity. The displayed current is 30 A; confirm the exact suffix and nameplate against the quotation.

System-voltage route

The source describes 12/24 V self-identification. Do not substitute a title voltage, auto-detection label or a different family branch for the selected unit.

PV input evidence

The visible source records 100 V cold-condition / 90 V at 25 °C PV Voc; 400 W at 12 V or 800 W at 24 V. Design calculations still need module temperature, series count, Voc tolerance, fuse/disconnect arrangement and the exact manual limit.

Battery and load scope

The tables use battery-type and load-control wording, but actual charge setpoints, BMS permissions, load output rating, cable size and protection remain configuration-specific checks.

Controller RFQ checks

Six checks before finalizing the controller

A complete RFQ separates PV-string limits, battery charging, DC loads, special functions, communications and documents.

Exact model and table cell

Request the full model/suffix, nameplate and current datasheet; identify the one current, voltage and PV-power cell that applies to the quoted unit.

PV string at site temperature

Provide module Voc/Vmp/Imp, series and parallel count, lowest module temperature, cable run and disconnect/fuse topology. Check cold Voc rather than a nominal array voltage.

Battery profile

State chemistry, nominal bank voltage, capacity, BMS limits and required charge/float/equalize settings. Lithium wording or a customizable-profile line is not an approved battery pairing.

Charge and load duty

Confirm charge current, DC load voltage/current, surge, low-voltage disconnect/reconnect, lighting/time controls and any required derating at ambient temperature.

Special functions

Confirm RS485, display, remote monitoring, wind/AC inputs, AC output or street-light functions only from the exact wiring diagram and option schedule.

Evidence and commercial scope

Request manual, wiring, protection/settings schedule, test and destination compliance evidence, supplied accessories, packing, warranty, sample, lead time and substitution controls.

Specification boundaries

Do not let a controller headline replace an electrical design

The controller is one part of the PV, battery, load, cable and protection system; final suitability requires the exact selected unit and installation data.

Source-record boundary

The displayed values belong to a controller family or selected member. Confirm the exact model suffix, nameplate, current revision and destination version before fixing an order specification.

Voc is not operating voltage

PV cold Voc, MPPT operating range and rated PV watts are different checks. A PV array must remain within every applicable exact-model limit under site conditions.

Battery labels are not compatibility approval

Lead-acid, gel, open-battery or lithium wording does not establish setpoints, BMS communication, current limits, temperature rules or warranty coverage for a specific bank.

Protection is system-specific

Controller protection labels do not replace correctly selected breakers/fuses, isolators, SPD, grounding, cable ampacity, enclosure, ventilation and commissioning tests.

Techfine controller FAQ

Questions to close before an exact-model quotation

These answers preserve the distinction between the current page record and a verified installation specification.

What current and voltage configuration applies to this PA30210 30 A MPPT controller?

The current source record shows 30 A and 12/24 V self-identification. Confirm the full model/suffix, nameplate and quoted table cell because title wording and shared family tables can differ.

Can the PV string be selected from the controller’s rated PV watts alone?

No. Check cold Voc, MPPT operating window, module electrical data, series/parallel layout, temperature, cable loss and every exact-model input limit before selecting the array.

Does battery-type or lithium wording prove compatibility?

No. Confirm chemistry, nominal voltage, charge/float/equalize settings, current limits, BMS requirements, temperature behavior and the supplier’s exact-model approval in writing.

Which documents should accompany the RFQ?

Request the exact datasheet, manual, wiring diagram, nameplate/model schedule, protection and settings information, supplied option list, destination compliance evidence, warranty and current commercial terms.
