- This is a multi-function inverter/charger, combining functions of inverter, MPPT 60A/80A solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.
The batteries voltage is completely fine but the inverter always beeps and goes off when it's night time with a 04 fault indicating low voltage and high load, even when nothing is consuming. However, there is no problem during the day when we don't have electricity? Please assist with a way forward! Do you think that the solar panels don't prioritise the charge of the batteries?
code 04 means the voltage of battery is too low，check whether inverter can charge for battery at day time or battery itself status is good or not？
Do i have to use a breaker or a fuse between the batery and the inverter [question mark]
of course
Good work team
My inveter is a MUST, 1800pv,Pure sine wave 3kw, l install with 2x 550w solar panels, connected in series, and also 2x 200HA, batteries connected in series
But when I switch on the inveter, the solar charge display to battery does not appear on the screen,
Please can you advise me, thnkyu

I have been using must 3.5kva for almost 2years now and it has been serving but I have been having this challenge for the past 2months, my inverter no longer charge consistently it keeps saying error 44... Please what do I do

The adapter sits whistling, although there is a charge in the batteries, what is the problem, brother
Please, why is my Must inverter making an unusual noise? Meanwhile, it's charging and functioning normally. Thank you!
Hello, under normal circumstances, the higher the load, the louder the noise, which is caused by the high-speed rotation of the fan.
Hi "How to manually choose when to use the inverter and avoid automatic activation during a power outage."

Why my must inverter always get 63 & 3 error code when on solar(no grid)
On grid - ok.

Hello, you can consult our engineers

Big thumbs up from me.
Is there harm in oversizing your solar panels to improve absorption on cloudy days?
Eg a 650w panel.
Will there be risk on a sunny day when 650 watt is actually absorbed by the panel when the inverter is only rated for 550 watt ?
My panel has a built in solar charge controller.
Please install according to the rated power requirements.
@MUSTENERGY I was expecting a little more info than that.
I'm two minded about this Panel.
Nobody answers calls or whatsapp messages.
And this is the feedback I'm getting from you.
@@rezo786 The inverter is safe within the power range it can withstand. However, you did not specify the model and details of your system.
@@MUSTENERGY same as the vide title, MUST

PV18 1012 VPK:
PWM 50A
Max. PV Array Open Circuit Voltage 55V
Therefore, the open circuit voltage (Voc) of the solar panel you choose cannot exceed 55V.
I already bought an inverter, but didn't buy batteries. Can I connect 220V AC to it and turn it on to check that it is working? Could it harm him?
This model needs to be connected to the battery to use
Please do a grid tied version
Bonjour comment on fait pour désactiver la sonnerie du niveau bas de la batterie
Merci
Comment on active la sonnerie? Plz in need
do you mean the alram beep on the inverter？ if yes，you can set 25 option as AOF

здраствуйте подскажите как должна называться модель в которой напряжение идет от солнечной батареи а недостающая мощность берется от сети? VPM или HM?

Hello MUST ENERGY , can the PV18-10 12 MODEL be used with only battery and solar connected ?
Can it work without grid connection ?
yes
Im really slow is the AC input running to the panel and AC output a generator receptacle?
12vx4 = 46v? do they sell 48v batteries? so you can use just 1 or 2 batteries? I wouldn't know what batteries to buy.
Thats why I wouldn't do it because I don't know if I put a switch for switching to the solar from the genny or transmission line. Im not sure..it kind of looks like a powerwall needs to be installed by someone that knows what there doing.
Its the other way around for the input and output, couldn't you use an interlock into the panel for the generator instead of the AC input with a switch? I don't know what the code is for that.
Does the input need the switch to the charge the batteries for the generator/transmission line? see thats what would of happened.
Is the inverter pure sine wave or modified sine wave?
pure sine wave
1000w 12v version, this battery is opitional to function of this inverter?

I noticed after a thunder strike my solar inverter tripped of and still not able to on till now. And I have a circuit breaker connected to it. Pls I need your help asap
Sorry, this question requires an engineer to answer. Please send your inquiry to service@mustenergy.com. If you have any pictures, you can also send them together. Thank you.

How do i charge my solar batteries with a generator, please help me.
you can send questions to our engineer's email service@mustenergy.com
Please , what kind of protections (fuses or mcb´s) are required?
My solar inverter is charging but is beeping and showing red light (fault) what does it mean
Hello, please send the details of your issue to our after-sales engineer's email(service@mustenergy.com). Thank you!
My inverter keeps on charging even if the battery is fully charged. What could be the cause?
If the charging current is very small, about 1A is normal, and the floating charge state ensures that the battery voltage is at a constant voltage.
@@MUSTENERGY my inverter is set at default on 20A….is it too much? Will it not affect the battery?

Hi
How I can enable silent mode in this inverter pv1800 3024vpm
I turn off 24 beep and 25 alarm
But didn't active mute on LCD...
I bought the 2/3kw model. Not good. Buy something instead
whats wrong with it? im looking at it but only cos its cheapest
Don't buy this. After 8 months mine stopped working. Went for repairs this week. Connected the unit and it started to spark like crazy and could have cause a fire. Be careful when you buy this product.
How are you?
