What this listing states. FCC, CE and RoHS stated in the listing, so safety scores 5 of 10. 24-month warranty stated in the listing. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 3 of 5. See How We Pick.
Inverter limits. Stay within the stated continuous watts (surge watts last only a moment), use the cable size and fuse the manual gives, ventilate it, and never connect an inverter to home wiring yourself; that is work for a licensed electrician.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For inverters, safety means stated certifications; none of the five picks state one in their titles or data. Two picks state a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| HONOURLIGHT 3000W Inverter | 9.5 | 29 | 20 | 20 | 0 | 3 |
| EGSCATEE 2000W Inverter | 9.5 | 28 | 20 | 20 | 0 | 3 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best power inverter for well pump
Watts and peak decide the pick
The HONOURLIGHT states 3000W with 6000W peak. The EGSCATEE states 2000W with 4000W peak. The FOVAL 200W states 200W. The FOVAL 150W and PiSFAU state 150W. Well pumps surge at startup, so compare the peak figure to the pump’s surge draw, not just the running watts. For minivan picks, see our best power inverter for minivan picks.
Outlets, USB and displays
The HONOURLIGHT states dual AC outlets, 3.4A USB, an LCD display and remote control. The EGSCATEE states 2 AC outlets, 3.1A USB and an LCD display. The three smaller picks are title-only listings with no stated outlets. For pure sine picks, see our best pure sine wave inverter for solar system picks.
| Inverter | Watts | Peak | Warranty |
|---|---|---|---|
| HONOURLIGHT 3000W Inverter | 3000W | 6000W | 1 year |
| EGSCATEE 2000W Inverter | 2000W | 4000W | 12 months |
| FOVAL 200W Inverter | 200W | Not stated | Not stated |
| FOVAL 150W Inverter | 150W | Not stated | Not stated |
| PiSFAU 150W Inverter | 150W | Not stated | Not stated |
Compare warranties
The HONOURLIGHT states a 1-year warranty. The EGSCATEE states 12 months. The three smaller picks state no warranty term. For water pump context, see our solar water pump vs electric pump guide.
Match the inverter to the pump
A well pump’s surge can be several times its running watts, so the 3000W and 2000W picks suit real pump loads while the 150W and 200W picks suit only the smallest pumps or controls. Check the pump’s stated surge figure before buying, and connect directly to the battery with high current terminals.
Sizing Notes
- Match stated watts: 3000 on the HONOURLIGHT, 2000 on the EGSCATEE, 200 on the FOVAL 200W, 150 on the other two picks.
- Check peak: 6000W on the HONOURLIGHT, 4000W on the EGSCATEE, none stated on the other three picks.
- Note the warranties: 1 year on the HONOURLIGHT, 12 months on the EGSCATEE, none stated on the other three picks.
- Check outlets: dual AC on the HONOURLIGHT, 2 AC on the EGSCATEE, none stated on the other three picks.
- Mind the USB: 3.4A on the HONOURLIGHT, 3.1A on the EGSCATEE, none stated on the other three picks.
