The Samlex EVO-4248SP inverter charger combines a 4200W pure sine wave inverter, adaptive battery charger, and automatic transfer relay in one integrated power system. It provides 120/240V AC split-phase output from a 48V battery bank.
Designed for demanding off-grid and backup applications, the EVO-4248SP can connect to a standard household electrical panel. It can support properly designed systems for off-grid cabins, remote work sites, alternative-energy installations, and emergency backup power.
The EVO-4248SP provides both 120V and 240V AC split-phase power. Its integrated 60A battery charger supports lead-acid and compatible lithium-ion battery systems, while the 40A transfer relay manages transitions between available AC power and inverter operation.
Key features include:
The adaptive charging system evaluates lead-acid battery conditions during the bulk charging stage. Later charging stages can then respond to battery condition rather than relying only on preset charging times. Equalization is also available when manually initiated for appropriate battery types.
A compatible 48V MPPT solar charge controller can be integrated through the EVO system’s external DC charging input. The system’s ONLINE Mode can also prioritize battery and inverter power over available grid power when properly configured.
When transferring from inverter operation to available grid power, the system synchronizes with the incoming waveform before transferring. When grid power is lost, transfer from grid to inverter is rated at less than 16 milliseconds.
The EVO-4248SP provides up to 12,600 watts of surge power to help start compatible high-demand loads such as compressors and refrigerators. Additional short-duration overload capability can help the system handle temporary power demands.
Multiple protection monitoring points continuously watch operating conditions and can initiate a protective shutdown when potentially damaging conditions are detected.
Five internal temperature sensors help control two variable-speed cooling fans. The fans operate when needed to help reduce unnecessary noise and energy consumption.
The optional EVO-RC-PLUS remote control, sold separately, provides additional programming and monitoring capabilities. It can also record system performance and fault information to a removable SD card for later review.
The EVO-4248SP is designed for properly engineered alternative-energy, off-grid, remote-site, backup, and emergency power systems. Installation and system sizing should follow manufacturer requirements and applicable electrical codes.
