Genasun Solar Controllers
Fanless, low-EMI Genasun MPPT controllers for 12V to 48V lithium and lead-acid battery systems.
Genasun MPPT Solar Charge Controllers for Demanding Conditions
Genasun solar charge controllers are made in the USA and used by scientific and military communities worldwide. They are compact MPPT controllers with no moving parts, rated to operate from -40°C to +85°C. They keep lithium and lead-acid batteries charged in remote, marine, off-grid and industrial installations where reliability matters more than anything else.
Low EMI for Communications and Telemetry
Genasun controllers are designed for low EMI, so radios, telemetry and sensing equipment keep working cleanly while the controller charges at full output.
Fanless, Lightweight Design
Genasun relies on advanced electrical design and firmware instead of fans or relays. With no fans to clog with dust and no relays to fail, these controllers suit long service life at unattended sites. Each unit weighs 80 to 185g and measures around 14.6 x 6.5 x 3.5cm, so it fits easily into tight enclosures, small boats and equipment boxes.
Voltage Boosting MPPT (GVB-8 Series)
The Genasun GVB-8 boost controllers step up the voltage from a standard 12V solar panel to charge 24V, 36V or 48V battery banks. Models are available for lithium and lead-acid chemistries, in standard and waterproof versions, plus a custom voltage lithium option. To compare other step-up options, see our voltage boost MPPT solar charge controllers.
How to Choose a Genasun Controller
Start with your battery voltage and chemistry, then match the controller current to your panel size. For broader sizing advice, read our guide to choosing the right solar charge controller.
- 12V lead-acid (AGM, Gel, flooded): 4A, 5A and 10.5A MPPT models, with load output and LVD on selected 5A units.
- 12V lithium (LiFePO4): 5A and 10.5A lithium models, plus the GV-5 and GV-10 at 12.5V and 16.7V charge voltages for specific lithium configurations.
- 24V, 36V and 48V banks from 12V panels: GVB-8 voltage boost controllers in lithium or lead-acid versions.
- Wet or exposed locations: choose the waterproof GVB-8 variants for marine and outdoor installs.
- OEM and product integration: Genasun 12V 5A PCB controllers for lead-acid, Li-ion and LiFePO4, plus the GV-5-MOD ribbon cable interface adapter.
All Genasun models include current input limitation, advanced fault tolerance and recovery, independent short circuit and reverse polarity protection, and auto restart once a short is removed. If you need a weatherproof controller but are comparing brands, browse our waterproof solar charge controllers.
