Ziewnic Solar Inverters

Ziewnic is a Pakistani inverter brand owned by ZIEWNIC PK (Pvt) Ltd, a Karachi company founded in 2014 that sells fourteen hybrid-inverter series plus LiFePO4 batteries and solar panels through independent retailers rather than its own storefronts. Across the three entry-tier hybrids SolarNevs verified, street prices ran Rs 104,999 to Rs 154,999 (verified 2026-07-25) — Ziewnic itself publishes no prices at all.

Who actually owns and builds Ziewnic?

The corporate side is unusually well documented for a local brand: ZIEWNIC PK (Pvt) Ltd gives a founding year of 2014, a physical head office — Office #5, 2nd Floor, Rehman Mansion, Regal Chowk, Shahrah-e-Liaquat, Saddar, Karachi — UAN 021-111-000-666 and a branch office in Deira, Dubai (ziewnic.com/about.php, fetched 2026-07-25), with an export arm at ziewnic.ae.

The manufacturing side is not documented at all: no factory, no OEM partner. Ziewnic's own PDFs claim "European Design and Engineered in Taiwan" (Z5 datasheet) and "Designed and Engineered in Taiwan" (Diamond datasheet), both fetched 2026-07-25 — the brand's claims about itself. Two observations are recorded without drawing a conclusion: the mode naming ON/OFF/MKS/KS and the sibling series names "Axpert Ultra Twin" and "Axpert Twin Premium +" match Voltronic Power's Axpert and MKS family, and the Android package identifier com.eybond.ziewnicsmart means the monitoring stack is Shenzhen Eybond's platform skinned as Ziewnic. Neither identifies a factory, and SolarNevs will not name one until a certificate, ODM disclosure or manufacturer statement exists. **On the evidence available, Ziewnic is also not a Deye rebadge* — that framing circulates about several Pakistani brands but nothing supports it here. {/ VERIFY */}

Is Ziewnic connected to Growatt?

Three things are sourced, and SolarNevs asserts nothing beyond them: Growatt PK (Pvt.) Ltd operates from the identical Karachi address as ZIEWNIC PK (Pvt) Ltd and resells Ziewnic alongside Axpert, Revo, Marvel and Lenox (growattpk.com, fetched 2026-07-25); "POWERED BY GROWATT PK (PVT.) LTD." appears in the footer of Ziewnic's own datasheet PDFs; and Growatt Pk Private Limited publishes both Ziewnic monitoring apps on the Apple App Store. Not established: the legal relationship between the two Karachi entities (no SECP filing was checked), and any relationship with Growatt New Energy of China — neither site claims one and no evidence was found. Search "Growatt Pakistan", land on growattpk.com, and you have found a Karachi reseller, not necessarily the Chinese manufacturer's channel. {/* VERIFY */}

What does Ziewnic actually sell?

The live product index carried fourteen series on 2026-07-25 — Axpert Ultra Twin, Axpert Twin Premium +, Atom, Diamond II, Diamond, Lenox 3.0, Lenox Hybrid, Li-Wall V-2.0, Marvel, Roux, Z-BOX European, Z5, Z6 and Max, plus a Lobo PV-converter line (a fully imported VFD replacement for solar pumping) — alongside LiFePO4 batteries and Tiger-series panels. Max and Z5 are the entry tier; Roux (IP54, aluminium body) and Lenox 3.0 (IP65, up to 16–20 kW including three-phase) sit above them. SolarNevs covers the three entry-tier hybrids:

One structural note on the Max series: it does not appear on Ziewnic Global's export site, the Max PV2500 showed sold out, and the Max Dual PV5000 was out of stock at two of three retailers on 2026-07-25. Status stays active because the SKUs remain on Ziewnic's live index, but the line looks Pakistan-only and thin on stock. {/* VERIFY */}

Why do Ziewnic prices vary so much between shops?

Because there is no anchor: Ziewnic publishes no price list, so every retailer sets its own. On 2026-07-25 the identical Z5 6G PV8500 sold for Rs 124,999 at Onestopmall.pk, Rs 125,000 at Idrees Electronics and Rs 145,999 at Power Plus Generator — a 17% same-day spread. Two structural traps follow:

1. Generation mislabelling. Retailers list "5G" and "6G" versions of the same PV6500 and PV8500 numbers under near-identical titles — one listing checked on 2026-07-25 was titled "4.5 (KVA) 5G PV6500" while its own body copy claimed "Real 6th Gen". The badge on the box decides what you own.
2. Model-name collisions. "MAX (5.5 KW) PV7000" and "MAX DUAL (5.5 KW) PV7000" sell as different products at roughly Rs 110,000 and Rs 153,000–154,999 (verified 2026-07-25). The word "Dual" carries about Rs 43,000.

SolarNevs found no evidence of counterfeit Ziewnic units on 2026-07-25 — no recall, no brand warning, no owner reports — but with no serial-verification portal that silence proves little; the documented risk is mislabelling. Buy through the Ziewnic Solar Energy Official Store on Daraz or a dealer on Ziewnic's own where-to-buy list, and photograph the rating plate before the installer walls it in.

How good is Ziewnic's service network?

Better documented than most local brands, and genuinely a reason to consider the marque: 18 branded service centres with street addresses, individual mobile numbers and 10:00–18:00 opening hours (ziewnic.com/service-center.php, fetched 2026-07-25), spanning Punjab, Sindh and Khyber Pakhtunkhwa from Karachi and Lahore to Vehari and Dera Ismail Khan. The gaps matter as much: no listed centre in Balochistan, none in Islamabad proper, none in Azad Jammu and Kashmir or Gilgit-Baltistan. A published address is not a repair outcome — SolarNevs has verified that the network exists, not what happens when you walk into it.

What is the warranty reality?

Five years on the Z5, Max and Diamond lines is printed on Ziewnic's own datasheets and echoed by every retailer checked on 2026-07-25; Roux is advertised as a five-year replacement warranty on the PCBA specifically; the Z-BOX European battery is listed at ten years and the Li-Wall 2.0 at six. What a claim actually looks like could not be established: no first-hand sourced account of one being honoured or refused was retrievable in either direction. The one negative primary signal — a Voice Of Customer PK post titled "Don't Buy This Crap - ZIEWNIC SOLAR INVERTER AND BATTERY" — had its body and comments withheld by Facebook, so its substance is unknown and will not be characterised here. Ask your dealer, in writing, who handles a claim and whether the unit travels to Karachi.

Does the Ziewnic app work?

There are two, both published by Growatt Pk Private Limited. "ziewnic inverter" (Android com.eybond.ziewnicsmart, iOS id6739390671) showed version 2.15.36 released 14 July, with too few ratings to display a score. The separate "ZIEWNIC" storage app (iOS id6505088409) carried 1.0 out of 5 from 4 ratings on the Pakistani App Store, reviewers reporting the sign-up form rejecting a valid email address as the wrong format (both fetched 2026-07-25). Four ratings is a tiny sample, but it is the brand's only numerically rated owner signal; Google Play's figures could not be read, so no Play Store score is published. Wi-Fi on Z5 and Max hardware is an optional dongle, not a built-in radio.

What has Ziewnic launched recently?

• Roux Series — first IP54-rated Ziewnic inverter, aluminium body, five-year replacement warranty on the PCBA (announced 2025-07-19).
• Diamond II Series PV 3000 and PV 4500 — "5 Years Warranty | 6th Gen Technology" (post dated 14 January; no year displayed). {/* VERIFY */}
• Li-Wall 2.0 lithium battery — 25.6 V and 51.2 V 100 Ah, 6000+ cycles, built-in Wi-Fi, 16-unit parallel, six-year warranty (post dated 11 February; no year displayed). {/* VERIFY */}

Fault codes and troubleshooting

Ziewnic units store fault codes (the Z5 datasheet lists a "Record fault code feature in program (25)") and Pakistani repair channels publish videos around Ziewnic faults 01 through 09, so an aftermarket repair trade exists. A published code table does not: ziewnic.com carries none and the manual is paywalled, so the Ziewnic error-code page ships with observed codes only.

Where Ziewnic sits against its rivals

Ziewnic's entry tier competes with the Inverex Veyron II 6kW, the Fronus PV5200 and the Crown Micro Xavier 3KW — all Axpert-class single-phase hybrids in the same retail channel. Inverex leads on demand (12,100 monthly searches against Ziewnic's 4,400, SEMrush Pakistan database, July 2026); Ziewnic's counter-argument is its documented 18-centre service list. SolarNevs has not independently verified those rivals' street prices and does not borrow numbers between pages. The brand's biggest gap for a buyer is not price — it is that with 4,400 monthly searches there is still effectively zero independent long-form owner discussion of these units on the open web.
