My landlady kindly installed a Dyness 5.12 battery (0.5) and inverter Deye. Our continuous draw is probably only about 15amps but we need to accomodate a spike of up to 40 amps for machines starting up on occasion. The installer has set the inverter to cut out when we go over 10amps. It’s driving us crazy. Any advice? Why can we not draw the 50amps the battery can handle …when we need it. ? They are suggesting we add another battery.. for another 10amps. Why so little? There is no solar. Yet.
