Application and Product
The record describes agricultural irrigation powered by a FU9000SI-2.2KW-SS2 solar pump inverter. It also refers to automatic start and stop operation as solar conditions change.
Source-Backed Project Records
Electrical Project Case Studies
UsFull Electric Co., Ltd. has supplied electrical products for solar pumping and PV protection projects outside China. The two cases below retain the technical facts published in the company’s earlier USFULL project records. Each case also states what the source does not disclose.
This distinction matters. A country name, model number, or daily water figure does not prove every design input. We show the published system configuration, explain why each item matters, and keep engineering assumptions separate from recorded results.
Two documented projects
Sri Lanka: 2.2 kW solar pump inverter. Mexico: 46 kW PV array, 37 kW drive, 30 kW pump, and six-string combiner box.
Company and Source Identity
Why These Records Link to USFULL
UsFull Electric Co., Ltd. was established in 2005 in Wenzhou, Zhejiang, China. The company presents its current English product and service information through UFELE Electric on ufele.com. The original Sri Lanka and Mexico project records remain on usfull.com under the earlier USFULL name.
We link to those original pages because a case study should preserve its source trail. The links let buyers compare this summary with the earlier record. They also make it clear which data came from a published project and which paragraphs provide current engineering context.
UFELE does not use anonymous buying scenarios as completed projects. Only the two source-backed records appear in the case list and structured data on this page. Future cases should follow the same rule: identify the application, show approved evidence, state the supply scope, and disclose important limits.

Documented Project 01
2.2 kW Solar Pump Inverter for Irrigation in Sri Lanka
The published Sri Lanka record identifies the FU9000SI-2.2KW-SS2 solar pump inverter. It reports that the irrigation system could deliver up to 100,000 liters of water per day under the project conditions. The application used solar energy to reduce dependence on limited or expensive grid supply.
Published Result
The source reports up to 100,000 liters per day. That figure describes the recorded system. It is not a guaranteed output for another farm, pump, season, or water head.
Record Limits
The public page does not state the pump model, pump curve, total dynamic head, module count, string voltage, site coordinates, measured test period, or project date.
| Published fact | What it confirms | What a new project still needs |
|---|---|---|
| FU9000SI-2.2KW-SS2 | The inverter model used in the recorded project | Motor voltage, rated current, phase, cable length and load compatibility |
| Agricultural irrigation | The application category | Total dynamic head, required flow, pipe loss and water source condition |
| Up to 100,000 L/day | The maximum daily figure stated by the source | Measurement period, solar resource, season, pump curve and operating hours |
Source check: review the original USFULL Sri Lanka project record. For a similar system, start with the solar pump inverter range and send the pump and site data for a separate selection review.
Documented Project 02
37 kW Solar Pump Drive and 6-String Combiner Box in Mexico
The Mexico record describes a hilltop irrigation system with a 46 kW PV array, a 37 kW / 40 HP 380 V solar pump inverter, a 30 kW submersible pump, and a six-string PV combiner box. Unlike the Sri Lanka record, it publishes the array arrangement and several protection component ratings.
PV Array
The source lists 84 solar modules rated at 550 W each. It groups them as six strings with 14 modules per string, giving a published array size of about 46 kW.
DC Collection
The six-string, 1000 V, IP65 combiner box included a 4P 100 A 1000 V DC MCCB, 1P 20 A 1000 V DC fuses, a 3P 1000 V DC SPD, and an anti-reverse diode.
Drive and Pump
A 37 kW / 40 HP, 380 V solar pump inverter supplied a 30 kW submersible pump. The public record does not provide the motor current, cable length, pump curve, water head, or measured flow.
| Project item | Published configuration | Engineering check for a new site |
|---|---|---|
| PV array | 84 × 550 W modules; 6 strings × 14 modules; about 46 kW | Confirm module Voc, Vmp, Isc, temperature coefficient and cold-weather string voltage |
| PV combiner box | 6 string, 1000 V, IP65 | Check maximum input current, cable entry, enclosure exposure and installation method |
| DC protection | 4P 100 A DC MCCB; 1P 20 A DC fuses; 3P 1000 V DC SPD; anti-reverse diode | Coordinate component ratings with string current, array short-circuit current and local rules |
| Solar pump inverter | 37 kW / 40 HP, 380 V | Match motor voltage, rated current, overload duty, MPPT input window and control functions |
| Water pump | 30 kW submersible pump | Verify pump curve, total dynamic head, cable length, flow target and dry-run protection |
Source check: review the original USFULL Mexico project record. Related product paths include PV combiner boxes, solar energy equipment, and solar pump inverters.
Evidence Comparison
What the Two Project Records Actually Prove
Both sources confirm a solar irrigation application and identify a UFELE or USFULL product. Their evidence depth differs. The Mexico record provides a system configuration. The Sri Lanka record provides a model and a reported daily water figure, but fewer design inputs.
| Evidence item | Sri Lanka record | Mexico record |
|---|---|---|
| Country and application | Yes — agricultural irrigation in Sri Lanka | Yes — hilltop agricultural irrigation in Mexico |
| Inverter identification | Yes — FU9000SI-2.2KW-SS2 | Yes — 37 kW / 40 HP, 380 V solar pump inverter |
| Pump identification | No pump rating or model published | 30 kW submersible pump; no model or pump curve published |
| PV array data | Not published | 84 × 550 W; six strings of 14 modules |
| Protection data | Not published | Combiner box, MCCB, fuse, SPD and diode ratings published |
| Performance statement | Up to 100,000 liters per day | No water head, flow or daily-volume result published |
| Public source | Original project page on usfull.com | Original project page on usfull.com |
The original sources support the facts listed above. They do not provide a complete engineering handover package, third-party performance verification, customer identity, commissioning report, or every field measurement.

Evidence Standard
What UFELE Will Add to Future Case Studies
A strong electrical case study needs more than a country and product name. When customer approval and records allow, UFELE will add a dated requirement summary, confirmed supply scope, product configuration, inspection points, installation evidence, and a measured result with its test conditions.
Real site photographs should identify the actual project. AI-generated or studio illustrations can explain system relationships, but they must not appear as proof of a factory, installation, commissioning visit, or customer result. The current images on this page serve as technical illustrations unless a caption states otherwise.
- Source identity: company, project record, date, and publication approval.
- Requirement: load, site condition, operating target, and constraints.
- Supply scope: exact products, ratings, quantity, and responsibility boundary.
- Review evidence: drawings, photos, datasheets, test records, and approved files.
- Outcome: measured result, test period, limitations, and follow-up status.

Data Needed Before We Compare Your System
A published case can show a product direction. It cannot replace a new selection. UFELE reviews each pump, PV array, and protection plan against the current site data and current product documents.
Pump and Water Duty
Start with the pump nameplate and pump curve. Add the voltage, phase, rated current, total dynamic head, required flow, daily water target, pipe length, and water source condition.
PV Array and Site
Send the module datasheet, proposed string layout, installation country, minimum temperature, ambient conditions, cable distances, and enclosure location.
Existing Equipment
If part of the system already exists, send clear photos of its labels, terminals, protection devices, wiring arrangement, and installation environment.
We then identify missing inputs, compare the operating voltage and current ranges, review protection needs, and confirm which details belong in the quotation or technical file. Final approval should use the exact model datasheet and order documents, not a value copied from a different case.
FAQ
Electrical Case Study Questions
These answers explain the source status, brand relationship, and limits of using a published project as a design reference.
Are the Sri Lanka and Mexico projects documented cases?
Yes. Both projects have public records on the earlier USFULL website. This page links to those records and separates their published facts from engineering comments and information that was not disclosed.
What is the relationship between UFELE and USFULL?
UsFull Electric Co., Ltd. uses UFELE Electric for this website and previously published the two source records under the USFULL name. Links to usfull.com preserve the original project sources instead of presenting copied claims without context.
Can I use the published system data for my own project?
Use it only as a reference. A new design still requires the pump nameplate, total dynamic head, flow target, motor current, module Voc and Vmp, temperature range, string arrangement, cable conditions and local protection requirements.
Why are some project details marked as not published?
The original records do not disclose every pump, site, commissioning or customer detail. Marking those limits prevents an assumption from becoming a claimed project fact. Customer names, exact sites, prices and private files also remain confidential unless publication was approved.
What should I send for a similar solar pumping review?
Send the pump nameplate, pump curve if available, voltage, phase, rated current, total dynamic head, required flow, daily water target, module datasheet, proposed string layout, site country and installation photos. UFELE can then review the product direction and identify missing inputs.
Send Your Solar Pumping or PV Protection Project
Share the pump, PV array, site condition, required flow, product ratings, photos, quantity, packing needs, and destination market. UFELE will review the product direction and identify the details that need confirmation before quotation.
