Using 1x300ah lithium with 200a constant draw but when I run loads ie small 900w kettle drawing 85a it cuts out and restarts with low battery. Have also used microwave with 1500w max input at various power settings and load gets to 145amps and cuts out am using 2awg cables 70cm long with 200a circuit breaker is there a specific setting I need or do I try with dynamic cutoff turned on even though victron advise it’s not relevant
Had some confusion between 2 awg and 2/0 awg so maybe if I double up the cable… anyway did a test again 900w kettle drawing 84 amp the bmv showed a voltage Drop down to 12.6v and inverter cut out changed dynamic cut out settings to 12v and tried again it went down to 12.5 and all good but tried microwave using 150a and inverter still cuts out then need charger turned on before inverter switches on again maybe the charge detected setting also needs changing I will reset inverter back to factory settings and try doubling the cable to see if voltage drop changes before investing in 70mm2- 0/2awg
Your battery cables are a little undersized ~ resulting in voltage drop between battery and inverter? Phoenix Smart Inverter manual.
Is your circuit breaker a quality unit? PPL have problems with cheapies.
