Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

HiSmart PV Combiner Box NV822287 is a DC combiner designed for small photovoltaic installations with one input and one output. The polycarbonate enclosure is rated IP67 and V0 (UL94) for waterproofing and flame retardance, and the unit includes MC4 connectors, a 1000V DC switch with a lockable handle and patented arc extinguishing chamber, and an integrated SPD for surge protection.

Advantages

The combiner box consolidates a single PV string and provides overvoltage protection and isolation on the DC side. Its IP67-rated, UV-resistant polycarbonate housing and lockable enclosure enable outdoor or rooftop installation. Built-in DC switch (1000V, 25A) and a 1000V/40kA surge protection device reduce wiring complexity while meeting relevant standards (EN60529, IEC 61643-31, EN 50539-11+A1, UL508i, IEC60947-3 Pv2).

Key specifications

How to use

Mount the combiner box on a suitable surface ensuring correct orientation and secure fastening. Connect the PV string to the input MC4 connector and route the combined output through the output gland to the inverter DC input. Use the DC switch to isolate the string during installation and maintenance. Verify SPD connections and grounding per local electrical codes before energizing the system.

Recommendations

For reliable operation, install the HiSmart NV822287 combiner box in accordance with applicable electrical and safety standards, use correctly rated MC4-compatible cables, ensure proper grounding of the SPD, and perform periodic inspections of seals, cable glands and electrical connections. Do not exceed the specified voltage and current ratings.
