Anton Marais Posted April 21, 2020 Report Share Posted April 21, 2020 Hi there Sorry very new to the program would like to now if theres a tutorial for a normal solar setup. Panels Inverter Mppt Charge Controller Lithium Batteries All i find is battery systems Another thing i would like to now is there anyway i can import victron products into the database?

Anton Marais Posted April 23, 2020 Author Report Share Posted April 23, 2020 So i have been trying this myself with no luck. I got so far as to add my own battery type and Inverter but the program still wants to add another inverter on top of the battery inverter and you cannot add any mppt chargers onto the battery inverter option. I dont want to add a battery system i would like to add a stand alone battery Another issue is i cant add a grid tie i have to make it a free standing system. Its as if the program is missing a option of "Grid Connected PV System with Electrical Appliances and Battery. Quote Link to comment Share on other sites More sharing options...
developer_mh Posted April 23, 2020 Report Share Posted April 23, 2020 Hi Anton, do you have a schematic drawing of your system? Perhaps we can find a system type that comes close to your application. But a pure DC coupled offgrid system is not possible right now in PV*SOL, I am afraid. Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
Anton Marais Posted April 23, 2020 Author Report Share Posted April 23, 2020 Hi There Thx for the response. Something like this. straight forward grid tie Quote Link to comment Share on other sites More sharing options...
developer_mh Posted April 23, 2020 Report Share Posted April 23, 2020 Hi Anton, the Victron MulitPlus II approach is somewhat different to our ongrid and offgrid system types. I'd interpret it as offgrid for the PV (as it does not feed into the grid), but ongrid for the loads (as loads are covered by grid energy). In case of grid outage, it would clearly be a DC coupled battery offgrid system: I think the most suitable way to model this in PV*SOL would be an offgrid system with diesel backup generator, and you interpret the generator energy as from grid energy. In offgrid systems in PV*SOL you can also define load shedding, which might be useful for this kind of application. Then, you define a PV inverter with the MPP tracker properties of the MPPT solar charge controller. The DC/AC efficiency would be your DC/DC efficiency of the solar charger. And then you need an offgrid battery inverter with the corresponding properties of the MultiPlus-II. This should give you results that are as close as possible with PV*SOL at the moment. Let me know if this helps. If you need any further assistance, please don't hesitate to ask. Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
Anton Marais Posted April 24, 2020 Author Report Share Posted April 24, 2020 Hi Martin Ill have a try. I already did it this way with off grid only issue here is you have 2 x inverters now one for the PVs and another for the batteries. The power figures will surely differ then?

developer_mh Posted April 27, 2020 Report Share Posted April 27, 2020 Hi Anton, yes, the power figures must be taken from the datasheet of the MultiPlus-II and then entered into PV*SOL either for the PV inverter or the battery inverter. You'll have these two devices in PV*SOL that represent the one MultiPlus-II device. Kind regards, Martin Quote Link to comment Share on other sites More sharing options...
