February 21, 20233 yr I recently got a 8KW Sunsynk inverter and soon they will deliver 2 x 5.12kWh Sunsynk Batteries. If I want to get 2 more batteries in the future can the inveter support it or would I need an additional inverter?

February 21, 20233 yr Author Will be getting 12 x 550-570 Watt Jinko Panels But still want to know what the max amount of 5.12kWh Sunsynk Batteries I can connect to the inverter before I am forced to get a second one. Edited February 21, 20233 yr by lavaland

The more the Marier, 20 KWH of batterie back wow, with that amount of PV you should be able to get through LS schedule 8
February 21, 20233 yr The 8kW inverter will only ever be able to deliver an 8kW output to your loads. The 2 Sunsynk batteries can in theory already supply up to 10kW. And if you add another 2 batteries, then your 4 batteries combined could supply up to a 20kW output. A second 8kW Sunsynk in parallel will in theory help you to make better use of the available instantaneous power. You've actually got some overkill using so many 1C Sunsynk batteries on an 8kW inverter, you could have used 0.5C batteries as well. There is no need to install another inverter if you don't need that extra instant power. You'll just take longer to drain your batteries through a single inverter than through two. More panels won't hurt. The inverter can handle over 10kW of panels. You will have 6.6kW of solar panels, and that should be about enough on most days to charge your batteries up again if you've drained them overnight, and supply some daytime loads but on some cloudy days you may need to top up from grid. The 8kW inverter should take 2-3 hrs to charge the bank up.
February 21, 20233 yr Author Thanks for the info Yea I dont need more instantaneous power. It is just to last longer in case that the power is down for extended amount of time. 1 - 3 days power outages becoming more common as infrastructure continues to decline in the area.
February 21, 20233 yr According to their website, it's either 8 or 16 as max: https://www.sunsynk.org/532kwh-battery (this isn't the exact model you have though) At the top it says Quote Sunsynk’s top-grade 5.32kWh Lithium-Ion Phosphate batteries have been engineered to the highest standard. They are capable of up to 80% depth of discharge and scalable up to 16 times, allowing for a maximum of 85.12kWh per inverter. In the specs listed it has: Quote Scalability: Max 8 batteries in Parallel I suspect it's 16 as this is quite a common number for the communication protocols. Edited February 21, 20233 yr by Hyarion
February 21, 20233 yr Naming threw me, this appears to be the 5.12kWh battery: https://www.sunsynk.org/ip65-battery Up to 32 in parallel for 163kWh 😅
February 21, 20233 yr 3 hours ago, Hyarion said: this appears to be the 5.12kWh battery: https://www.sunsynk.org/ip65-battery That particular battery in the link is one of their latest models and comes in an IP65 housing and still very uncommon here. On / off switch at bottom etc, not top left. BYD cells, but 32 max in parallel is the number they state. Not sure whether the same parallel specs apply to the 5.32kwh or the other 5.12kwh batteries by SunSynk (the website is not very clear as to which has BYD and which has CATL cells but apparently not compatible with each other so OP take note when expanding system later). The incompatibility was mentioned to me by SunSynk support and a tech guy at one of the agents.

LOL) He who dies off grid WINS ha ha
April 12, 20233 yr The 5.32 can be 8 in parallel (Scalable from 5.32 to 42.56 kWh) Sunsynk_SUNBAT_5.32_WallMounted_UserManual_v2_English.pdf
April 13, 20233 yr I have a 8Kva Sunsynk with 18 x 550W Canadian Panels, 2 x 5.12KW Freedom Tower Batteries. What's the best combination on my panel connection so that I don't overload my MPPTs. TerryM

August 22, 20241 yr Hi. I have same type of issue. I recently got an 8kw Phocos inverter and 2 Phocos Any-Cell batteries. How many solar panels should I add to charge from them as I don't want the utility company to be doing that with their unreliable erratic power.

What is the size of the batteries in kWh each and also in what time frame in hours do you want to charge them back to full. Also provide the % of capacity you intend discharging the batteries.

How many solar panels should I add to charge from them as I don't want the utility company to be doing that with their unreliable erratic power. If you have the Phocos 5kwh battery(100ah) module the max charge current is 75A. I would charge and discharge these batteries at 0.5C so 2 batteries in parallel 100 Amps. So you can work on 4.8kwp for charging but you need to include the load demand that is unknown. To give you decent advice we need your inverter scc spesifications and your load power during a 24h stint or even better your utility bill or your prepaid kwh consumtion for 2 months to average accurate consumption. Peak load during winter and time of day. To do accurate planning on solar array needed there is many varables that needs to be taken into account. The battery specs state that 1 module can discharge @100A ( 1C) so 2 batteries in parallel 200A that would be able to run the 8kw at full power 185A drawn from batteries but like i said my motto don't charge/discharge above 0.5C. 6 hours ago, Scorp007 said: What is the size of the batteries in kWh each and also in what time frame in hours do you want to charge them back to full.
