The HGM420N model can be controlled via the remote start input or the front panel buttons as well. **Q: I have an off grid solar system. Can this unit be programmed to auto turn on the generator when the solar batteries run down to a certain level?** A: Unfortunately, this controller does not monitor the battery bank voltage. You can check this controller instead: SmartGen HGM4020T Mobile communication base station + dual power ATS+RS485 https://www.amazon.com/SmartGen-HGM4020T-Mobile-communication-station/dp/B07GH5HNV6 **Q: This product ships from? hgm400n series** A: Currently we are shipping this item from our stock in Europe. **Q: will this detect a power outage?** A: Yes. This controller detects power outages, start generator and switches load circuits to be powered from generator. When the grid comes back, it switches load circuits back and stops generator. All necessary delay settings could be configured. ## Frequently Bought Together - LASETO SMARTGEN HGM420N Automatic Start Generator Controller (AMF) - Savior Generator Petcock Fuel Gas Tank Switch Shut Off Valve for Predator Champion Generac Etq Homelite Husky Powermax Replace 0j0974 (16mm x 1.5mm) - YAMAKATO 196cc 212cc 224cc Generator Air Filter w/Housing Cover Box Air Cleaner Assembly for 3000 3500 4000 4500 watt Champion Predator Firman Generators… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/83778552-smartgen-hgm420n-automatic-start-generator-controller-amf](https://www.desertcart.ae/products/83778552-smartgen-hgm420n-automatic-start-generator-controller-amf) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-09-01*
