Customer ServiceStep3: Check if the <discharge maximum current> setting is too low. Refer to the inverter''s manual for the maximum value; for example, the X3-Hybrid G4 has a maximum discharge current of 30A to ensure the battery can output at full power.
Customer ServiceWhen selecting the charge and discharge current limits you will always be limited to the lowest current value whether that is the inverter or the batteries. For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge
Customer ServiceI''m confused as the Quattro is reporting a current draw of 2.10 amps to power a 76W AC load (indicating inverter loss of ~33W, which seems a little low, I would expect 60W) but the DC Power for the rest of the system is showing as 68W which is way higher than it should be. I''m only running a Cerbo, BMV and some MPPT''s which basically
Customer ServiceAnother concern is that battery voltage is also strongly dependent on battery current due to battery inherent resistance. In particular the discharge current lowers that voltage, the so called kettle effect. That means that under heavy load the battery voltage will reach the limits of settings 12 and 29 earlier than with little load.
Customer ServiceBatteries should never be fully discharged, and certainly not left in discharged state. It should also be noted here that the voltage of a battery that is in use is not a good measure for its level of discharge. Battery voltage is affected too much
Customer ServiceThe calculated 41A is the current from the battery. That''s 500 watts /12V = 41.7A. The current on the AC side will be 500W/220V = 2.3A. There will be losses in the inverter, meaning that you will need even more current from the battery than calculated. You need to find a battery protection module that can handle much more than 40A. To be safe

Customer ServiceWhen selecting the charge and discharge current limits you will always be limited to the lowest current value whether that is the inverter or the batteries. For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current. Two 5.12/5.32kWh batteries have a continuous discharge of 100A. This means that the maximum charge/discharge
Customer ServiceA power inverter converts direct current (DC) from the battery to alternating current (AC) for powering various devices. When you use a power inverter, it draws power from the car battery. Prolonged use of the inverter may cause the battery to discharge quickly, especially if the vehicle is not running. The battery may not receive sufficient
Customer ServiceAll inverters have a difference between what is being drawn from the battery and what is being used to power loads. If you divide the load value (2169) by battery draw (2843) your current efficiency is 76%. Several factors affect this percentage.
Customer ServiceThe battery protect is unidirectional. Meaning is cannot charge and discharge through it. What you can do is set the inverter to switch off on battery voltage and SOC. Set your system to shut off around 10% SOC min to allow for cell imbalances at lower soc. The victron 12v charger should wake up the other battery.
Customer ServiceI''m confused as the Quattro is reporting a current draw of 2.10 amps to power a 76W AC load (indicating inverter loss of ~33W, which seems a little low, I would expect 60W) but the DC Power for the rest of the system is showing as 68W which is way higher than it should
Customer ServiceThe battery capacity, or the amount of energy a battery can hold, can be measured with a battery analyzer. (See BU-909: Battery Test Equipment) The analyzer discharges the battery at a calibrated current while measuring the time until the end-of-discharge voltage is reached. For lead acid, the end-of-discharge is typically 1.75V/cell, for NiCd
Customer ServiceRecommended Measure: 1: The current battery SOC has reached or is lower than the preset discharge cut-off SOC value : Check the parameters: 2: The battery is not allowed to discharge, for example, the BMS allows the discharge
Customer ServiceThe battery discharge rate has a direct impact on the inverter''s performance because it affects how much power the inverter can draw from the battery at any given moment. Higher discharge rates allow for more power to be drawn from the battery, enabling the inverter to handle larger loads. Conversely, lower discharge rates limit the amount of power the inverter
