Huawei, Sungrow and Solis inverters: compare exact models
In this guide
Huawei, Sungrow or Solis: how should you compare the offers?
Choose the offer that identifies the exact model, capacity, installation scope and who handles warranty claims. Ask suppliers to complete the same fields for each option before comparing final totals. Get a missing model or work cost filled in first.
Keep total panel capacity in kWp separate from inverter output in kWac. If you plan to add a battery later, ask for the compatible battery model, extra equipment and warranty effects in writing. A “hybrid-ready” label alone does not establish the cost or what can be connected.
If sound is part of your decision, ask for the exact model’s published sound rating and test conditions, if available. Compare ratings only when the measurement conditions match. If the unit may be near a bedroom or living area, ask the installer to explain siting options and the constraints for this project. A Lowyat post captured on 29 September 2026 asks whether a Hoymiles hybrid inverter is very noisy [source]; it is a buyer question, not a sound test, and it does not describe Huawei, Sungrow or Solis.
Use the worksheet below to choose between actual offers. A brand name alone does not establish reliability; this page has no comparable failure data to rank Huawei, Sungrow or Solis.
A dated package-price example
Trexon Energy listed these “from” prices on a page updated 17 March 2026. They are one advertiser’s examples on that date. Before buying, request a fresh quote with exact models and an itemised equipment, installation, fees, tax and exclusions breakdown.
| Package and panel capacity | Solis | Huawei | Sungrow |
|---|---|---|---|
| Starter · 5.58 kWp [source] | From RM16,499 | From RM18,499 | From RM19,499 |
| Popular · 8.68 kWp [source] | From RM20,499 | From RM22,499 | From RM23,499 |
| Large · 19.84 kWp [source] | From RM35,999 | From RM37,999 | From RM38,999 |
What does the extra price buy?
In each dated example row above, Huawei minus Solis is RM2,000, and Sungrow minus Solis is RM3,000. Those are arithmetic differences between the listed package prices, not separate inverter prices or a measured brand premium.
For your offers, calculate total difference = offer B’s final total − offer A’s final total after both include the same work, fees and tax. Ask the installer which model, features, warranty or service changes for that extra amount. Compare any stated labour, travel or shipping charges payable during a claim as well. A lower total is not equivalent when items remain excluded.
For card or instalment offers, do not choose on monthly payment alone: request the same-scope cash price, total financed amount, tenure, monthly payment and stated fees or terms. Compare financed total with cash total; pay more only if the written offer identifies a feature, service or warranty coverage you value.
Fill in the actual offers by brand
A brand name does not answer who will support the equipment after installation. Record each dated offer in the matching column, and write “not stated” when its documents leave something out. One buyer’s experience with a claim or replacement time does not establish every seller’s arrangement; ask for terms specific to the quoted model and project.

Frequently asked questions
Which brand is better or more reliable?
This page has no like-for-like long-term failure data to rank reliability. Compare exact models, applicable features, warranty text, claim contacts and quote scope.
Is the price difference between brands fair?
Do not treat a package gap from another date or a single seller as the current market standard. Ask the installer to itemise model and price within the same system scope.
What should I ask if a battery may be added later?
Ask the provider in writing for the inverter topology, compatible battery models, extra equipment, controls and warranty effects; do not judge from a "hybrid-ready" label alone.
What should I check if inverter noise matters?
Ask for the exact model's published sound rating and test conditions, if available. Compare figures only on a like-for-like measurement basis. If the unit may be near a bedroom or living area, ask the installer to explain this project's siting options and installation constraints. One user's note about another model is not a measurement for Huawei, Sungrow or Solis.
