Hi all, Our apartment association is considering going for partial solar solution to meet its needs and below is our requirement – Our monthly association EB usage is around 700 units. We are looking at installing a 2.5 KW solar system (with hybrid inverter) that will help us eliminate day time genset backup during summers. We would like this system to supply to 2 fans connected in each of 15 flats in our apartment to the common (association) EB grid. We would like to explore the feasibility of net-metering since beyond the backup, we have scope to route back to the grid and save on costs – esp. since we are falling in the highest slab of EB tariffs. Our association EB connection is a 3-phase system that supplies for a lift, motor and common lights. We are not looking for battery bank backup because of the above exclusive day time requirement. Location: Hyderabad, Andhra Pradesh Some questions we have are: 1. We are assuming that ‘Islanding Protection’ will ensure that in scenario of grid-failure or load shedding, our solar system would still be active within our apartment for the select points we have planned for. Is this a correct assumption or is it total shutdown/blackout if the grid fails? 2. Is the above setup feasibile with net-metering? Esp. since our solar generation is partial and is required to meet the daytime backup for select points (for which wiring is already in place – for genset backup). We only want to avoid daytime genset backup and save on the cost – esp. during summer load shedding. 3. Is the 20% AP state subsidy announced only for net-meter or is it for the entire system? Is this subsidy available for off-grid solutions as well? 4. MNRE indicative costs are way less than what it practically works out!! MNRE guideline cost for a SPV system without battery is Rs.100 per watt. 2.5 KW (without battery) guideline cost = 100*2500 = 250000 After MNRE 30% subsidy = Rs.175000 If AP state subsidy of 20% is applicable = Rs. 140000 I have since enquired with three top companies and I am getting quotations raging from 3Lakhs to 3.5 Lakhs!!! And this is post subsidy, which is makes it almost twice the guideline cost!! Am I missing something or is there plenty of scope for negotiations :)? Thanks in advance for you expert opinions/suggestions. Thanks & Best Regards, Srinivasan M

Hey, i just want to know whether 4 x flooded 150 ah 12v batteries connected in series (so 48 v 150 ah battery) and 4 x 65 ah 12 v smf batteries (so 48 v 65 ah battery) can be connected together in parallel to a 3525 va utl inverter?

I did some research here and there and i dont seem to find the ideal solution for me.
I live in Aizawl,Mizoram. The state electricity board supports Net Metering. Every time there is heavy rain, the electricity board cuts off electricity for safety reason (the infrastructure is very poor here in the hilly region). Moreover there is constant repair work going on every other day, making electricity extremely unreliable. An inverter is a default standard equipment in all homes here!
So what we want to do for our new house is install a 10 KW ON-GRID Solar System with Net Metering enabled, which helps reduce overall cost of our electricity, and also need a power backup system with 20-30 batteries to provide us electricity during the frequent electricity cut offs. The batteries should work only when the electricity board cuts off the electricity.
Can anyone provide me links to the dealers and the equipment i will need as well as the estimated cost?
