The SE-C Series is an early Gerixi MPPT solar charge controller family designed for off-grid battery systems using 12 V, 24 V, 36 V or 48 V batteries. The family includes 40 A, 60 A and 80 A charging-current options, giving distributors a practical way to match controller capacity to the solar array, battery bank and expected load.
Why the SE-C family is useful for product selection
Buyers often compare charge controllers by current rating alone. A better selection starts with the complete system: battery voltage, battery chemistry, PV open-circuit voltage, expected charging current and installation conditions. The SE-C family keeps the basic product logic clear. A 40 A model can suit a smaller battery-based system, while the 60 A and 80 A versions provide more room for larger PV arrays and higher daily energy demand.
How to compare the 40 A, 60 A and 80 A options
- SE4840C: 40 A charging current with a compact 180 x 185 x 75 mm housing.
- SE4860C: 60 A charging current in a larger enclosure for systems with greater charging demand.
- SE4880C: 80 A charging current for higher-capacity off-grid solar projects.
These ratings should not be treated as a substitute for array calculations. The selected controller must match the battery voltage and the expected maximum charging current. The installation should also leave sensible operating margin instead of sizing every component at its absolute limit.
Check PV voltage and battery chemistry together
The SE-C product information lists an 18 V-150 V PV open-circuit voltage range and support for lead-acid, LiFePO4 and lithium batteries. The open-circuit figure is a design limit, not a promise that every panel combination in that range is suitable for every battery voltage. Cold-weather PV voltage, series connection and the controller settings should all be checked against the exact installation instructions.
Installation points for distributors and system builders
- Confirm the supplied controller version and battery system voltage before wiring.
- Connect the battery first, then the PV array, and then the DC load.
- Set the charging profile for the actual battery chemistry and verify the protection settings.
- Check cable size, fuse or breaker selection, ventilation and enclosure temperature.
- For a wholesale order, confirm the exact model, charging current, PV configuration, destination market and documentation.
For distributors, the main advantage of the SE-C Series is the clear range structure. It can cover several battery voltages and charging-current requirements while keeping the product conversation focused on system matching. Ask Gerixi to confirm the exact supplied configuration, customization scope, minimum order quantity and technical documents for the target market before placing an order.
