8kva Solar Inverters

ELS_Solar_INV_8 is an integrated system consisting of a solar charge controller, transformer-based inverter and an AC (mains) charger. Batteries are charged either through solar (PV), grid (mains) or with sharing of current (PV and Mains). The system gives priority to solar power first and uses grid power only when solar power and battery charge is insufficient to meet the load requirements. When the battery is fully charged the system will automatically turn on the inverter to supply the load.

Features:

• 60min backup time @2000W load (16x 100Ah Batteries, no solar panels).
• 4hours backup time @4000W load (16x 100Ah Batteries, no solar panels).
• 5 hours backup time @6000W load (16x 100Ah Batteries, no solar panels).
• Automatic utilization of available solar power.
• Preference to solar power when available.
• Pure sine wave output inverter.
• Heavy duty battery charger with current sharing.
• Multi stage battery charger.
• Smart overload and short circuit protection.
• LCD display to monitor the system.
• Transformer-based Inverter (increased reliability and maintainability).
• Email notifications for alarms (Overload, Battery Low, No DC, Grid Failure, Low battery protection alarm).
• Bypass mode: Bypass the inverter and switch grid power to the load with a switch on the front panel.
• Auto Generator start function: The inverter has a relay output that can be used to start a generator. The generator is started if there is no grid, battery or PV power available. This function can be turned on and off with a switch on the front panel.
• The system has two power plans to choose from. SMB (Solar, Mains, Battery) and SBM (Solar Battery, MAINS). SMB will prioritize Solar over mains (grid power) and mains over battery power. In SBM mode Solar will be prioritized over battery power and battery power over mains.
