Using a Muitiplus 24/3000/70 (with 800AH AGM bank) to power a self-build mobile café.
Initially using shore power during operation due to high demand appliances and battery power for (the fridge) overnight.
Now when shore power is shut off, low batt alarm sounds (despite 98% SOC) until it is reconnected.
also, the inverter is never functioning though 'on' and AC-in is not charging the batteries, when viewed on the color control..?
As well as this problem, I worry that the batteries are not being discharged and recharged enough to keep them healthy, as the power is always coming from the grid and not the bank.
Can I set the multiplus to use the batteries down to a safe minimum level, ignoring the grid connection,and then charge them up fully again...while also using shore power as 'power assist' to cover spikes in demand from appliances..?
Just joined the forum, so many thanks for any advice,
