hdupreez Posted May 4, 2022 Posted May 4, 2022 Hello All, I need some advise with configuration settings. I have 2x Sunsynk 5kW inverters configured in a master-slave configuration, with 24x 410W solar panels and 3x 6.4kW BSL batteries connected in parallel. My question is regarding the battery charge and discharge current. If a single BSL battery has a recommended charge current of 50A and a max discharge current of 105A, is that the values I must set on each inverter or should I half or double the values because of the master-slave configuration? The BMS is only connected to the master inverter. Also, what value do I specify for the grid charge current? For instance, if I want a maximum of 2500W grid power to charge my battery, it should be 2500/48V which is about 52A, but do I need to account for 3x batteries or the fact that I have 2x inverters that can simultaneously charge the batteries? The manual is not very clear on this. All help will greatly be appreciated Quote
DaveK Posted May 14, 2022 Posted May 14, 2022 Same question - do I put all info in master or divide it between both inverters?? Quote
power.esrl3 Posted May 18, 2022 Posted May 18, 2022 (edited) Amps and Power should be divided by number of inverters as per my experience. Its silly these big names dont have proper documentations. Edited May 18, 2022 by power.esrl3 spelling Quote
Richard van Antwerpen Posted December 6, 2022 Posted December 6, 2022 Hi Guys, I also need assistance with a similar but different setup. I have a site is 3 Phase and has 6 x Sunsynk 8kW inverters running as master and slave for each of the phases we then had 3 10kWh Sunsynk batteries. The only issue was that the batteries did not last. Then an additional 10kWh battery was added and now the system trips on loadshedding. Is there a specific method of adding a battery to this config or setup config that my installer has missed? Quote
