Solar Inverters
Solar Inverters — Grid-Tied, Hybrid & Off-Grid
Nastech supplies solar inverters from Solis, SMA, Huawei and Jebel at wholesale, with stock across our regional hubs for fast delivery into MEA, Asia and emerging markets. Use the guide below to choose the right type and size, then click through to full datasheets and specs.
Which inverter type do you need?
The first and most important decision — it shapes both cost and capability.
| Type | Best for | Notes |
|---|---|---|
| Grid-tied string | Reliable grid, no storage — most commercial rooftop & utility work | Lowest cost per kW, highest efficiency, simplest to service |
| Hybrid | Backup, self-consumption, load-shedding — most projects in our markets | Manages panels, battery & grid in one unit. If the client mentions outages, choose hybrid |
| Off-grid | Remote sites, rural electrification, telecom towers | Battery mandatory; sizing is stricter with no grid to fall back on |
Single-phase or three-phase?
Determined by the site's supply and system size, not preference:
- Single-phase — residential and light-commercial, typically up to around 12 kW.
- Three-phase — commercial and industrial, and anything above the single-phase ceiling. Balances load across phases.
Watch-out: match the inverter's phase to the site's actual supply — the most common (and expensive) spec error is caught on site.

Common questions
How do I size an inverter to my array?
Size by the DC-to-AC ratio — total panel watts divided by inverter watts. For the high-irradiance conditions across our markets, a ratio around 1.2 is a sensible starting point; modest array oversizing captures more energy without significant clipping. Confirm the string voltage sits inside the inverter's MPPT window across temperature extremes.
Hybrid vs string — what's the difference?
A string (grid-tied) inverter converts DC to AC with no battery — cheapest and most efficient where the grid is reliable. A hybrid manages panels, battery and grid together, essential wherever backup or self-consumption matters.
Which battery works with a Solis hybrid inverter?
Compatibility depends on voltage class (HV vs LV) and communication protocol. We confirm tested-compatible inverter-and-battery pairings from our portfolio — ask for a compatibility check with your quote.
Do you supply wholesale / project quantities?
Yes — wholesale supply with stock across regional hubs for MEA, Asia and emerging markets, from single systems to bulk project volume.
