-8% SaleAdvanced 5kW single-phase hybrid inverter with dual MPPT, 40–60V battery support, IP66 protection, UPS switching, and intelligent energy management.
The Solis S6-EH1P5K-L-PLUS is a high-performance 5kW single-phase hybrid solar inverter designed for residential solar energy storage systems. It supports 40–60V lithium-ion and lead-acid batteries, providing reliable backup power while maximizing self-consumption of solar energy. Featuring dual independent MPPT trackers, the inverter can handle up to 10kW recommended PV array capacity with a 500V maximum PV input voltage. It delivers seamless UPS-grade backup switching in less than 4ms, ensuring uninterrupted operation for essential household loads during power outages. The inverter also supports parallel operation of up to six units, generator integration, smart load management, and remote monitoring through the SolisCloud platform using optional WiFi, LAN, or GPRS communication. Its IP66-rated enclosure and natural cooling design ensure reliable outdoor performance with minimal maintenance.
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
Size battery DC cabling for the continuous 112A load by using at least 35mm² or 50mm² flexible copper cables. Install an external 160A DC-rated breaker between the battery bank and inverter to protect against direct shorts and eliminate thermal voltage drop.
Connect the communication bus using shielded Cat6 cable to the inverter's CAN port when configuring 48V/51.2V LiFePO4 batteries. This gives the inverter live access to individual cell voltages and temperatures, eliminating the guessing errors of voltage-based lead-acid profiles.
Mount the inverter on a shaded wall away from direct afternoon sunlight, even though it has an IP66 outdoor rating. Direct ambient temperatures over 45°C will initiate thermal derating, reducing maximum daytime charging speeds to safeguard power transistors
Keep string operating voltages between 200V and 400V (typically 6 to 8 units of 550W panels per MPPT) to hit peak conversion efficiency. Never exceed the 500V open-circuit threshold (Voc) under cold morning ambient conditions
A1: Yes, this inverter supports battery-free operation by routing power directly from active solar panels to critical loads during daylight hours. However, because solar output fluctuates with cloud movement, pairing the unit with a 48V battery bank is strongly recommended to maintain steady voltage and prevent load drops.
A2: The inverter runs continuous combined loads up to 5,000W and handles 10,000 VA motor startup surges for 10 seconds. This allows it to simultaneously operate a 1.5-ton inverter air conditioner, a refrigerator, a 1HP water pump, internet routers, ceiling fans, and household lighting without overloading
A3: Yes, it provides pre-configured CAN and RS485 communication protocols for all major 48V and 51.2V LiFePO4 battery manufacturers. It continuously reads battery State of Charge (SOC), cell balancing, and temperature telemetry, while also supporting lead-acid and tubular gel batteries via manual settings
Yes, the unit includes an integrated export power management controller that works with the included Eastron smart meter to export power or enforce strict zero-export limits. Users can sell excess units under Bangladesh net metering policies or limit backfeed if local transformer approvals are pending
A5: Yes, up to 6 units can be connected in parallel on the AC backup and grid ports to build systems up to 30kW. These networked units can be configured for high-capacity single-phase output or synchronized across phases to establish a 400V three-phase microgrid
