HQST Promo Codes for October 2026

Solid kit, few minor issues

I bought the 400W Solar Kit to put on my RV. The panels and the 40A MPPT Charge Controller seem like good quality for the price. Everything arrived well-packed. Installation was mostly smooth, but the included Solar Extension Cables were a bit shorter than I expected for my setup, so I had to get some longer ones locally. The instructions were okay, but a few more diagrams for wiring up multiple panels would have been helpful for a beginner like me. Overall, it's a decent value and it's working well to keep my batteries topped off.

Works as advertised

Got a 190W Monocrystalline Solar Panel. Delivery was prompt. Panel performs exactly as stated. Good quality.

Awesome power inverter!

I just received my 2000W Pure Sine Wave Inverter and it's fantastic! I hooked it up to my battery bank in the remote cabin and it powers everything I need without a hitch. The build quality feels really robust and it's surprisingly quiet. I was a bit worried about pure sine wave inverters being expensive, but this one was a great price for the performance. I'm already planning my next purchase from HQST, maybe a bigger battery! Definitely recommending them to my friends who are also into off-grid living.

Great deal on the battery

I was looking for a 100Ah LiFePO4 Lithium Battery for my van build and kept an eye out for sales. HQST had a good discount on it, and with free shipping, it felt like the best value compared to other brands I checked. The battery arrived quickly and was well-packaged. It's been performing as expected, holding a charge really well. I saved a decent amount by waiting for a deal, which made the whole purchase feel very worthwhile. Happy with the purchase and the savings.

Good panel, easy setup

I got the 100W Monocrystalline Solar Panel for my little shed. Shipping was pretty quick, took about 4 days to get here. The panel itself felt solid and setting it up with the Z-Brackets was straightforward. It's been charging my battery just fine. No complaints, it does what it's supposed to do.
