Can I ask for opinions on this quote from Rosen solar for my off grid plan please ? I have come up with this formula to run a 1670 sq ft passive house , with all needs for two people and an annual consumption of less than 4000 kwh per year . many thanks , Graham

I am installing an off grid sliding gate opener a BFT Deimos AT 600(kg) , to a 6 metre steel/ timber gate and would like to hear your opinions, please on the best way to power it up ? It uses 70w at 24 volts so my current thinking is 2x12vx 15 amp batteries in series and 2x 12v 40w...

Right , I have had enough . I have pleaded begged and threatened rosen solar for solutions to problems I have had with the 10 kw system I bought from them in 2020. The mails/ messages / phone calls have been ignored . I live off grid using only their system and it has been a frustrating...

I have 2x 200 amp batteries at full charge , 99% + they will only read 114 amps the other 1x battery reaches 200 amps ok , All are the same 9.6kw Li type , installed at the same time and use the same PV array to charge . Battery reset has been tried but made no difference . Whichever...

Can I ask for some advice please , I am installing my Rosen Solar off grid system . I have 4 x strings of 7 x 400 w panels into a combiner box , and have 2x Growatt 5k inverters which involves a 36 metre cable run . I have 100M rolls of cable 1x black , 1x red to carry the power ...

Both my spf5000 off grid inverters shut down when not enough power is being drawn from them . It's been a mystery for a while but the get around is to always have something switched on so they don't get to 100% Searching through the settings I came across number 43 which was showing 58.4...

Has anyone found a remote display for Growatt inverters that can be placed inside a house ? I have 2 x inverters and Shine wifi display sent to my phone , which works well but would like to see a permanent wall display .

Hi from Greece , I have watched a lot of discussion on Off Grid systems here and although I surely am still at the beginning of a solar career , I think this is the system that would suit my needs . We are building a passive type house and have no grid within affordable distance ...

A fortunate position to be in ? I have 3x 200ah Li batteries in the off grid system and with 28 x 400 watt panels feeding a normal size house , my batteries are always in a fully charged state . I am always looking for things to use up power , even converted the oven from gas to electric . I...

New 48v system off grid . we have 4x 100 amp li batteries on one inverter , also 2x 100 amp li batteries on another inverter. Can both be connected to one AC board to house supply ? Right now they have no BMS comms between them and are fed ,,full by solar . The 4 batt system is connected to...

One of my 2 x SPF5000TL HVM off grid Inverters has stopped charging , I am waiting for Growatt to sort it out but need to know if the 2 different inverters can work together on the same off grid system ? The 5000 ES and SPF5000TL are same basically but will they work alongside each other ?

I bought 3x of Rosen 9.6kw batteries A/B/C and have been using them in an off grid house . 5 months back one of the BMS failed and I bought 3x new BMS boards expecting further failures . C was changed and worked well , integrated with A/B well . Now C has failed , so naturally assumed it...
