PV1800 VPM High Frequency Off Grid Solar Inverter Installation Video

[@silasaniceto8096]

Do i have to use a breaker or a fuse between the batery and the inverter [question mark]

[@MUSTENERGY]

of course

[@mnhlapo2763]

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?

[@MUSTENERGY]

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？

[@oneononestories8499]

Please, why is my Must inverter making an unusual noise? Meanwhile, it's charging and functioning normally. Thank you!

[@MUSTENERGY]

Hello, under normal circumstances, the higher the load, the louder the noise, which is caused by the high-speed rotation of the fan.

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

Please contact our engineers [e-mail]

[@rezo786]

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.

[@MUSTENERGY]

Please install according to the rated power requirements.

[@rezo786]

@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.

[@MUSTENERGY]

@@rezo786 The inverter is safe within the power range it can withstand. However, you did not specify the model and details of your system.

[@rezo786]

@@MUSTENERGY same as the vide title, MUST Pv181012 vpk

[@MUSTENERGY]

@@rezo786 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.

Can we connect Must inverter 3.2 kW and 3 kW in parallel?

[@jamesmutuma6381]

Is the inverter pure sine wave or modified sine wave?

[@MUSTENERGY]

pure sine wave

[@anatoliikorzh7917]

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?

[@MUSTENERGY]

This model needs to be connected to the battery to use

[@martijnbaarn]

Hello MUST ENERGY , can the PV18-10 12 MODEL be used with only battery and solar connected ? Can it work without grid connection ?

[@MUSTENERGY]

yes

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

Hello, you can consult our engineers [e-mail]

[@RevivedWarrior1]

Im really slow is the AC input running to the panel and AC output a generator receptacle?

[@RevivedWarrior1]

12vx4 = 46v? do they sell 48v batteries? so you can use just 1 or 2 batteries? I wouldn't know what batteries to buy.

[@RevivedWarrior1]

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.

[@RevivedWarrior1]

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.

[@RevivedWarrior1]

Does the input need the switch to the charge the batteries for the generator/transmission line? see thats what would of happened.

[@brianmajola1808]

My inverter keeps on charging even if the battery is fully charged. What could be the cause?

[@MUSTENERGY]

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.

[@brianmajola1808]

@@MUSTENERGY my inverter is set at default on 20A….is it too much? Will it not affect the battery?
