Hi, unfortunately I'm not able to tell what the grid voltage is but it's good to have a possible explanation My main concern is the changing behavior when there is no grid power, battery only

Yes, lights also dim while a kettle is on

Oh, as a way to diagnose between batter/comms vs inverter? That would be awesome!..... but no, no panels yet. I am hoping to get installed soon but of course can't proceed to the next stage until this is sorted. Unless I can find a very helpful solar installer during these crazy times....

Hi, I had a LuxPower LXP 5 KW and Dyness A48100 installed about a month ago. I've experienced the following - maybe someone can tell me which are normal and which are indications of a problem? - After about 3 weeks of being able to comfortably power 2.5 kw of appliances during load shedding, 1.4 kw became an issue -- certain lights in house going dim for the duration, and e.g. microwave making a different sound from usual. Installer updated LXP firmware and reset settings and the issue went away, but a couple days later it came back again. - Inverter makes a relay clicking sounds about every hour. I understand a few should happen after load shedding as it tests if eskom power is fully up(?), and when it stops and starts charging battery. But this goes on all through the night when there is no load shedding, and no battery being used at all. Some of it is the inverter trying to re-top-up an already 100% battery, but I think there are more clicks that don't have a corresponding spike in the app. - Settings seem extremely unintuitive. Has anyone found an explanation of what they actually do in combination? (The manual just restates the name of the setting in slightly different words)

I spoke too soon. Once again, light go dim and appliances make funny sound, at at least 1.5 KW. It was fine when first installed. It was fine for two or three days after the installer upgraded the firmware. Installer denies there is any issue because the inverter is not giving fault codes Any ideas how to diagnose whether the issue is inverter or battery comms? Something objective that can prove without wiggle room that *something* in the system is either faulty or misconfigured?

Thanks, it looks like Beat, hoohloc and Bobstar all guessed right about it being related to the inverter -- the installer has upgraded the firmware and reset a bunch of settings and the problem seems to be fixed. (Apparently Luxpower settings cause confusing results you wouldn't expect?) Thanks for so many quick responses

Thanks for replies so far, but I see I should have been more specific My microwave + rest of the house total 1.45 to 1.5 KW. For a 50V battery that should be 30 amps, right? Someone said recommended amps is 50. Is 30 amps really considered "right up against" the limit?? How is that not false advertising? This is not a case of lights flicking. I understand that is normal. This is a case of lights going 50% brightness for as long as the microwave (or whatever) is using power. Installer originally told me the battery should be able to do 3600 kw in bursts, but doing that for too many minutes will overheat it.

I have Dyness A48100 + 5kw LuxPower LXP Discharge limits are set to 100% and 60 amps. When I use microwave or air frying, certain lights go very dim, and the appliance makes slight revving sound instead of constant hum as usual. My installer is trying to tell me, of course the lights will dim when you use the microwave or air fryer because you are getting close to the amp limit of the battery. Don't use any "heavy" appliances during load shedding. Is this correct, and Dyness's 0.5C is basically false advertising, or am I being scammed into accepting malfunctioning battery or inverter?

Hi there, I see there was some disagreement in this thread. Was this question answered? (regarding essential load:) "Does this mean that the AC load is limited to 5KW or does the inverter have passthrough capability so that the max demand of the on-grid loads can be achieved (of course up to the breaker limit on the the DB)?" People are saying the LXP 5kw is equivalent to Sunsynk and Deye (presumably also 5kw). But from the spec sheet and my installers, I'm gathering it has no pass-through ability -- can't use grid power to assist with essential loads. Sunsynk/Deye can do up to 35 amps == 8kw, but LXP is limited to 5kw (or even worse, 5kw for 30 seconds, then 4kw, according to spec sheet?)

Hi, I'm trying to work out what the 4kw and 5kw limits of the LXP apply to. If it can use 8kw of solar, does that mean it could use a max of 5kw to power essentials and non-essentials, and also use 3kw to charge batteries? Also trying to figure out if it has pass-through like Synsynk/Deye (blend in grid power to get over 5kw of essentials, up to 35 amps). Installers are saying no it doesn't, and must be protected by a 25 amp breaker.
