Byline

The HENGLAN engineering team.

Every technical article on this site carries the same byline, because the work is done by a team rather than a named individual: selection engineers, a documentation lead, and the people who run the factory test bench.

What the team actually does.

The team reviews load lists and returns configurations, sizes battery strings against a stated runtime, writes the model tables and the single-line diagrams, and runs the factory acceptance tests. The articles on this site come out of that work: the questions that keep arriving from project buyers are written down once, with the arithmetic shown, instead of being answered by email each time.

How an article is checked.

  1. 01

    Drafted from a real engineering question

    Each article starts from a load list, a commissioning problem or a recurring buyer question — not from a keyword list.

  2. 02

    Numbers checked against the catalogue

    Capacity ranges, power factors, transfer times and battery figures are taken from the model tables on this site, so an article cannot contradict the product page it links to.

  3. 03

    Reviewed by a second engineer

    The draft is read for the case where the advice is wrong: the load the product cannot carry, the grid condition where it fails, the sizing shortcut that breaks.

  4. 04

    Re-checked when the catalogue changes

    If a series is discontinued or a rating changes, the article that cites it is corrected in the same release.

What this byline does not claim.

It is not a personal credential, and it is not a substitute for a site survey. The articles describe how the equipment behaves and how to size it; they cannot confirm the measured voltage, the actual load or the earthing at your site. Those come from a load study, and every configuration on this site is quoted on the assumption that one has been done.

Corrections.

If an article is wrong about a standard, a formula or a rating, send the page and the correction. The page is amended and the modified date at the foot of the article changes. Articles are not silently rewritten: the date shown is the date of the last substantive edit.
